Shiju 0ea0d31020 fix(supervisor): restore canonical stdin after connection loss (#3852)
* fix(supervisor): restore canonical stdin after connection loss

Probe idle SSH peers and enforce a receive deadline during transport I/O,
including writes blocked by a stalled relay. Release the dead attachment's
stdin lease through existing handler cleanup.

Retry denied write intent on later ordinary input without displacing a
healthy owner. Preserve explicit read-only, EOF and detach behavior, and
discard control bytes retained while input ownership was denied.

Cover half-open forwarding, blocked writes, healthy idle peers and competing
reconnects through the production supervisor frame bridge and real SSH.

Fixes #3648

* docs(skills): describe read-only reconnect input retry

Explain what an openshell-cli user sees when automatic recovery reattaches before the supervisor closes the dead connection: the attachment reports read-only, later ordinary input retries stdin acquisition and prints `input enabled`, input typed while read-only is discarded, exit keys still detach, and an explicitly read-only viewer or a healthy owner is never affected.

krishicksandEvan Lezar a875add234 feat(server): write gateway OCSF events to JSONL (#3264)
* feat(server): write gateway OCSF events to JSONL

Previously, gateway security activity was available only in diagnostic output,
and events not associated with a sandbox, such as TLS certificate reloads, had
no independent structured record.

Now, configuring `openshell.gateway.ocsf_log` writes every gateway-produced
OCSF record to a bounded JSONL destination independently of `RUST_LOG`. The
destination supports daily or disabled rotation, retention limits, queue bounds,
and optional schema downgrade to OCSF 1.1 or 1.3.

Additionally, existing gateway emitters (TLS reloads, service routing, and
policy approval and auto-approval audits) emit structured events, so they reach
the JSONL destination, console shorthand, and the affected sandbox's log
stream. Records identify the gateway by its configured name in `device.uid` and
`device.name`, shared across replicas, with `device.hostname` identifying the
replica and `device.os` the gateway's operating system. Metrics and warnings
expose known best-effort losses.

50230616d5 refactor(runtime): retire Community image dependencies (#3386)
* feat(sandbox): default to official Alpine sandbox image

default_sandbox_image() now returns docker.io/library/alpine:3.22, a generic
version-qualified official image, so a fresh install no longer depends on the
community sandbox image catalog. All compute drivers (docker, podman,
kubernetes, vm) inherit this fallback.

* feat(deploy): default deployment configs to the official Alpine sandbox image

Update the shared gateway default_image, Helm chart values, the standalone
Kubernetes manifest, and the dev gateway task scripts to use
docker.io/library/alpine:3.22 instead of the community base image, consistent
with default_sandbox_image(). GPU e2e image-build base is left unchanged (CUDA
needs a glibc base).

* feat(driver): default to numeric non-root identity for USER-less images

With the default sandbox image now Alpine, images that declare no OCI USER
must start instead of being rejected. When the image declares no USER and
the policy requests none, the Podman and Docker drivers now supply a numeric
non-root identity (DEFAULT_SANDBOX_UID/GID = 1000) instead of rejecting,
matching the numeric-identity behavior of the Kubernetes and VM drivers. The
supervisor's resolved-identity path runs the sandbox as a synthesized
non-root account without the account existing in the image. Images that
declare a USER keep the OCI resolution path unchanged.

0a770d9173 feat(kubernetes): support HA gateway rebalancing (#1868)
* feat(kubernetes): support HA gateway rebalancing

Signed-off-by: Drew Newberry <anewberry@nvidia.com>

* perf(server): cache peer connections, tokens, and owner lookups

Every forwarded relay rebuilt its setup from scratch: an owner lookup, a
blocking read of the peer token, a TLS connect to the owning replica, and
a TokenReview plus Pod GET on the receiving side. Sandbox service routing
does this per HTTP request, so the apiserver calls scaled with traffic.

Cache all of it on ServerState:

- peer channels pooled per endpoint, so relays multiplex over one
  connection instead of redialing
- peer tokens keyed by SHA-256, expiring at min(ttl, token exp) so a hit
  cannot accept an expired token
- owner records for 3s against a 45s ownership TTL, still freshness
  checked before use

Entries are evicted when a relay fails. Also raise HTTP/2
max_concurrent_streams to 1024, since pooling funnels every relay between
two replicas onto one connection and hyper's default of 200 sits below
the 256 pending-relay budget.

Signed-off-by: divesh <dgude@nvidia.com>

* perf(server): pool upstream connections for sandbox services

Each HTTP request to a sandbox service opened its own supervisor relay,
paying a new TCP connection and HTTP/1 handshake every time. Worse, it
counted against the 32 in-flight relay cap, so a service handling more
than 32 concurrent requests failed outright.

Pool idle upstreams per endpoint and port, up to 8 each for 15s. Reuse is
safe because the pool only returns a connection hyper reports as ready,
and HTTP/1 cannot start a request until the previous body has drained.
Upgrades are never pooled since they take the connection over, and a
failed send evicts that endpoint. Pruning is bounded per key, with the
full sweep limited to once per 30s.

* fix(server): address HA gateway review findings (#3449)

- Let a gateway own supervisor sessions without a peer endpoint. Requiring
  one whenever the store is PostgreSQL broke every single-instance
  PostgreSQL deployment, because no sandbox supervisor could connect.
  A cross-replica request to an owner that advertises no endpoint now fails
  immediately naming the cause, instead of retrying until the wait timeout.
- Close a supervisor session on heartbeat only when another replica owns it,
  or after renewals fail for the ownership TTL. A database error no longer
  drops every session heartbeating during an outage.
- Clamp owner record ages at zero so a skewed or corrupt stored timestamp
  cannot produce a negative age.
- Bound the cross-object advisory lock with a lock timeout, so a stuck holder
  fails instead of blocking every mutation in the fleet.
- Refuse to start when a peer endpoint is configured on a multi-replica
  backend but peer authentication is unavailable, and warn when a
  multi-replica backend has no peer endpoint at all.
- Reject a plaintext peer endpoint when the gateway serves TLS.
- Skip the sandbox watch poller on single-replica backends, where the local
  update bus already sees every write.
- Rate-limit the peer owner cache sweep so an insert no longer scans the
  whole map under the lock.
- Retry GET and HEAD on a pooled upstream the sandbox closed, instead of
  returning 502, and drop an emptied endpoint from the pool right away.
- Document the gateway peer environment variables and the post-rollout
  ownership skew operators should expect.

krishicks cbf026366d fix(ocsf): require network activity endpoints (#3355)
Previously, Network Activity could be constructed without a source or
destination endpoint, allowing connection, accept, relay, and configuration
events to violate the OCSF 1.8 endpoint constraint.

Now, NetworkActivityBuilder requires a source or destination endpoint at
compile time. Connection failures identify the workload peer or genuine
transparent destination, listener failures identify the listening endpoint,
and mediation-lane failures use Application Lifecycle rather than fabricated
network endpoints. Malformed forward requests use HTTP Activity with a
method-only request, generated 400 response, and workload peer.

Additionally, Unix relay-channel events use Base Event, policy-validation
warnings use Config State Change, and the unused bypass monitor is removed
because the current isolation architecture no longer uses it.

krishicks 481ce566e1 fix(ocsf): correct HTTP activity context (#3316)
Previously, metadata events omitted both HTTP request and response objects,
early proxy rejections used HTTP Activity without request context, and
unsupported-scheme events did not expose enough safe HTTP context to satisfy
the OCSF 1.8 schema.

Now, metadata events include a method-only request and their actual HTTP
response codes without recording the metadata URL. Unsupported-scheme events
also include a method-only request plus the generated 400 response. Authority
mismatches and credential-resolution denials use HTTP Activity with their
generated 403 or 500 responses, and HTTP activity IDs are derived from the
request method.

Additionally, HttpActivityBuilder now enforces the OCSF request-or-response
constraint at compile time.

Shiju fd3fd9cf74 feat(sandbox): explain failed calls to external tool servers (#3207)
Show configured tool server addresses and their last observed connection
results together in sandbox status. Keep sandbox lifecycle readiness
separate so an external connection failure does not mark the sandbox unready.

Expose direct endpoint records through the CLI and SDKs, with plain-language
failure explanations and gateway acceptance times. Keep observation tracking,
runtime reporting, and gateway validation in dedicated endpoint status modules.

Preserve bounded reporting, request attribution, retry ordering, and
configuration and supervisor authority checks. Clear obsolete observations
while retaining the configured addresses, and document the distinction
between an observed HTTP response, current availability, and tool success.

Akram Ben Aissi 08eac8c46d fix(sandbox): detect an available login shell instead of hardcoding /bin/bash (#3147)
* fix(sandbox): detect an available login shell instead of hardcoding /bin/bash

The built-in default sandbox command and the interactive SSH session
hardcoded /bin/bash. Minimal images such as Alpine ship only /bin/sh
(BusyBox ash), so sandbox startup failed with an opaque "No such file or
directory (os error 2)" that never named the missing binary.

Add openshell-core::shell with shell-path constants and a runtime
detect_login_shell() that resolves a shell present in the sandbox image
($SHELL if executable, then bash, then /bin/sh). Use it for:

- the built-in default command (only the default is remapped; explicit
  user commands are never rewritten), resolved in the supervisor so it
  inspects the sandbox filesystem rather than the gateway's
- the SSH interactive shell
- the SHELL environment variable

Also name the program in the spawn error so a missing shell/binary is
diagnosable instead of a bare ENOENT.

Refs #3146

Signed-off-by: Akram <akram.benaissi@gmail.com>

* fix(sandbox): drop $SHELL preference in shell detection

$SHELL is image/user-controlled and the detected shell is later invoked
with `-lc`, so an executable that is not a compatible shell (e.g.
SHELL=/bin/false) would pass the executable check and then break command
execution even when /bin/sh is available. Resolve only from known shell
paths instead.

Also add a USR_BASH constant for /usr/bin/bash rather than a string
literal in SHELL_CANDIDATES.

Refs #3146

* fix(sandbox): resolve the default login shell in the supervisor (empty command = default)

Addresses review: interactive PTY SSH now uses the detected shell, the shell
tests are portable across the Windows lane, and default-shell provenance is
carried without a new spec field.

An omitted command is left empty end to end and resolved in the supervisor,
which is the only place that sees the sandbox image:
- The CLI forwards the command as-is; the gateway persists an omitted command
  as empty (no baked /bin/bash -l) and requests a TTY.
- MainProcessConfig carries the command empty (the transport now allows it);
  the supervisor resolves a login shell that exists in the sandbox image (bash
  when present, otherwise /bin/sh on minimal images like Alpine) and logs the
  resolved shell.
- Interactive PTY SSH (spawn_pty_shell) uses the detected shell; a shared
  build_ssh_shell_command helper covers the PTY and non-PTY paths, with a
  deterministic sh-only regression test.
- Unix-only shell tests are gated with cfg(unix).

An explicit command is always run verbatim.

Characterization tests for behavior that later work changes. No behavior
change.

- Pin the `openshell logs` output format, so a change to how that text is
  produced shows up as a diff rather than passing silently.
- Cover the supervisor log push layer.
- Assert OcsfEvent survives a JSON round trip. Serialization is written
  by hand and deserialization dispatches on class_uid into independent
  per-variant paths, so a field can serialize correctly and still be
  dropped or rejected on the way back in.

Polite_realism 60a9b4dc62 fix(ssh): add EMFILE backoff and exit notification to SSH accept loop (#2705)
Apply the same two-layer defense from the proxy accept loop (#2369/#2370)
to the SSH accept loop: classify transient vs terminal accept errors with
exponential backoff on EMFILE/resource-exhaustion, and notify the sandbox
when the accept loop exits so the container terminates instead of running
without SSH access.

- Add SshAcceptAction enum and classify_ssh_accept_error in ssh.rs,
  mirroring the proxy pattern (EMFILE/ENFILE/ENOBUFS → Retry with
  backoff, unknown errors → Terminal after 10 consecutive failures)
- Replace the bare accept().await in run_ssh_server with a classify-and-
  retry loop; resets consecutive-error counter on each successful accept
- Thread ssh_exit_tx: Option<oneshot::Sender<()>> through run_process;
  hold it as a drop-guard inside the SSH spawn so the receiver fires when
  the task ends for any reason
- Wire ssh_exited future in lib.rs (created only when ssh_socket_path is
  Some) and select! on it in both process_enabled paths, returning an
  error so the sandbox container restarts

  otherwise separated by audience alone, so a verifier that neglects to
  check `aud` could accept a gateway credential. The header is a second,
  independent discriminator.
- Publish OIDC-shaped discovery at `/.well-known/openid-configuration`
  so a service configured with only the gateway URL can learn the exact
  expected issuer and the JWKS location. It is shaped, not compliant:
  `issuer` is the gateway identity, not the serving URL.

Audience agreement:
- `MiddlewareManifest` and `InterceptorManifest` gain `expected_audience`.
  The audience is otherwise configured independently on each side of the
  boundary, where a mismatch surfaces only as an opaque authentication
  failure on every call. OpenShell now compares the two and fails at
  startup. An empty field keeps the check off for existing services.

Compatibility:
- Add `allow_insecure_transport` per registration. Enabling gateway JWT
  signing previously made any plaintext endpoint a hard startup failure,
  including the endpoint form used in our own documentation. The opt-out
  attaches no credential, is refused by the gateway if a supervisor asks
  for one, and warns at every startup.
- Make the transport requirement kind-aware. A middleware endpoint must
  be reachable from every sandbox supervisor, so only interceptors may
  use a gateway-local Unix socket.

Credential lifecycle:
- Replace the process-global slot map with a supervisor-owned
  `ExtensionCredentialStore` shared explicitly across the gateway
  connections the supervisor opens, removing test-order coupling.
- Rotate only when a credential is missing or has passed four fifths of
  its lifetime. Configuration polling ran every ten seconds against
  fifteen-minute credentials, so each poll re-ran gateway effective-policy
  resolution and re-minted the gateway token.
- Bound credential minting per sandbox, since each request resolves the
  caller's effective policy.

* docs: record alpha extension authentication in RFC appendices

Restore the RFC 0009 and 0010 bodies to their accepted text and move
every extension-authentication update into appendices instead. An RFC
records a decision at a point in time; superseding detail belongs
alongside it rather than rewritten into it.

RFC 0009's appendix carries the shared contract: claims, authorization,
key distribution, the `allow_insecure_transport` replacement for the
body's `allow_insecure`, and residual risks. RFC 0010's records only
what differs for interceptors and links to it. The existing
protocol-extensions appendix, which parked the phase 2 transport
question, now points forward to what was built.

Also document the audience handshake, the discovery endpoint, the
`typ` requirement, and `jti` replay guidance in the extensibility and
gateway configuration pages, and correct the middleware transport
guidance: middleware endpoints must be reachable from sandbox
supervisors, so Unix sockets are not an option there.

Jim Meyer 8c7dd148a9 perf(net): set TCP_NODELAY on latency-sensitive TCP hops (#2220)
* perf(net): set TCP_NODELAY on all tunnel and proxy TCP hops

The sandbox tunnel added ~44 ms of latency to every small
request/response because no socket in the path disabled Nagle's
algorithm, so sub-MSS writes waited on delayed ACKs at each hop.

Set TCP_NODELAY on every latency-sensitive TCP socket:

- gateway: accepted connections on the public listener (gRPC relay
  frames and WS tunnel writes)
- CLI: edge tunnel local accept + underlying WebSocket TCP stream,
  insecure TLS connector (tonic's default connector already does
  this), and service-forward accepted sockets
- supervisor: direct-tcpip connect into the sandbox netns, TCP relay
  target dials, egress proxy accepted connections, and all upstream
  CONNECT/HTTP dials (via a new connect_upstream helper)

Setting TCP_NODELAY on connect is best-effort: a failure only costs
latency, so we log and continue rather than fail the connection.

The sandbox SSH transport rides a unix domain socket and gRPC client
channels use tonic defaults (nodelay on), so no change is needed there.

Fixes #2219

* refactor(net): house TCP_NODELAY helper in a shared net module

Address review feedback on the TCP_NODELAY change:

- Move the shared set-nodelay helper out of supervisor_session into a
  new crate-private `net` module in openshell-supervisor-process, so
  ssh and supervisor_session no longer reach across modules through a
  pub(crate) item.
- Make the best-effort comments at each call site terse and consistent.

No behavior change; the benchmark ladder reproduces the same numbers.

* refactor(net): consolidate TCP_NODELAY helpers into openshell_core::net

Move the best-effort TCP_NODELAY helpers into the shared openshell_core::net

- Add set_tcp_nodelay_best_effort (accepted/existing streams) and
  connect_tcp_nodelay_best_effort (dial + set) with unit tests.
- Migrate all call sites in openshell-cli, openshell-server, and the
  supervisor crates to the shared helpers.
- Remove the crate-private net module from openshell-supervisor-process.
- Document socket guidance in AGENTS.md (Network Sockets).

* perf(net): set TCP_NODELAY on exec bridge and metadata server

The gateway-side single-use SSH-over-relay loopback bridge and the
sandbox IMDS metadata server were missed latency-sensitive TCP hops.
Set TCP_NODELAY on the accepted client connection and both russh client
dials of the exec bridge — interactive keystrokes and line-buffered PTY
output are the most tinygram-heavy traffic in the system — and on the
metadata server's accepted connections.

Also log unrecognized MaybeTlsStream variants in the edge tunnel so a
future TLS-backend change surfaces a silent TCP_NODELAY miss instead of
skipping it quietly.

Signed-off-by: Jim Meyer <jim@meyer4hire.com>

* perf(net): set TCP_NODELAY on openshell-sdk socket paths

The openshell-sdk crate landed on main with its own copies of the CLI's
hand-rolled sockets, which the CLI and TUI are meant to consume. Give
them the same treatment as the CLI equivalents:

- edge_tunnel: the accepted local tunnel connection and the WebSocket's
  underlying TCP socket (plain and rustls variants).
- transport: the dial in InsecureTlsConnector, tonic's custom-connector
  path.

Only these hand-rolled sockets need it. Tonic's own connector defaults
tcp_nodelay to true and applies it itself, so plain Endpoint::connect
callers were already covered.

The log prefix value passed to nft contains colons (e.g.
openshell:bypass:sandbox-cc817378:) but was not wrapped in double

the bare colons cause a syntax error that silently prevents all
bypass-attempt LOG rules from installing.

Wrap log prefix values in nft-quoted strings via a new nft_quote()

Varsha 8a14b3a477 fix(sandbox): skip read-only mounts during recursive chown of /sandbox (#2341)
* fix(sandbox): skip read-only mounts during recursive chown of /sandbox

The sandbox supervisor crashed with EROFS when the recursive chown of
/sandbox encountered read-only submounts. This is common in gVisor-based
Kubernetes deployments where read-only volume mounts are the only way to
enforce per-directory immutability (Landlock is unavailable under gVisor).

The fix adds two guards to the ownership walk:

1. Mount-boundary detection via st_dev comparison — paths on a different
   filesystem than /sandbox are skipped entirely, avoiding the chown
   call on nested read-only mounts.

2. EROFS tolerance — if chown still returns EROFS (e.g. the root mount
   itself is read-only), the error is logged at debug level and startup
   continues.

Symlink skipping (already present) is preserved and extracted into the
recursive walker for consistency.

Manually verified on a kind cluster with a read-only PVC mounted at
/sandbox/readonly-data: the pod starts successfully, writable paths are
owned by the sandbox user, and the read-only mount retains root
ownership. Kubernetes e2e test coverage is a separate follow-up.

Closes #2294

nested under a read-only directory on the same device (e.g., a writable
emptyDir inside a read-only ConfigMap mount sharing the same st_dev).

Now the EROFS case falls through to the directory recursion so that
writable children are still chowned.

Also fixes the doc comment which said EROFS errors are "logged as
warnings" when they are actually logged at debug level.

Seth Jennings 6461677c32 feat(policy): accept numeric UIDs for sandbox process identity (#1973)
* feat(policy): accept numeric UIDs in sandbox process identity validation

Allow run_as_user and run_as_group to be either the literal 'sandbox'
or a numeric UID/GID within [1000, 2_000_000_000]. This removes the
hard dependency on a baked-in 'sandbox' user in container images,
enabling compute drivers to inject resolved UIDs at sandbox creation.

Phase 1 of #1959.

* feat(supervisor): accept numeric UIDs for process identity dropping

Allow run_as_user and run_as_group to be numeric UIDs/GIDs, removing
the hard dependency on a baked-in 'sandbox' user in container images.

Changes:
- validate_sandbox_user(): accepts numeric UIDs without passwd lookup
  (logs OCSF event); keeps passwd check for "sandbox" name; rejects
  non-numeric non-sandbox strings that fail passwd lookup
- prepare_filesystem(): passes numeric UIDs/GIDs directly to chown()
  instead of requiring a passwd entry
- drop_privileges(): resolves numeric UIDs/GIDs directly via UID::from_raw
  / Gid::from_raw; skips initgroups when target uid matches current euid;
  uses guard conditions before setgid/setuid calls
- session_user_and_home(): falls back to ("{uid}", "/sandbox") for
  numeric UIDs, avoiding a passwd lookup that will fail

Re-exports MIN_SANDBOX_UID and MAX_SANDBOX_UID from openshell-policy
so callers have consistent range constants.

Phase 2 of #1959.

* feat(driver-kubernetes): resolve sandbox UID/GID from config or OpenShift SCC annotations

Phase 3 of the numeric-UID plan: allow operators to specify explicit
sandbox_uid/sandbox_gid in Kubernetes driver config, auto-detect from
OpenShift SCC namespace annotations, and propagate resolved values to
supervisor container env vars and PVC init container securityContext.

Changes:
- Add sandbox_uid/sandbox_gid fields to KubernetesComputeConfig
- Add SANDBOX_UID/SANDBOX_GID env var constants to openshell-core
- Implement resolve_sandbox_identity() to fetch namespace annotations
  and auto-detect OpenShift SCC UID ranges (sa.scc.uid-range)
- Pass resolved UID/GID through SandboxPodParams to pod spec builder
- Inject SANDBOX_UID/SANDBOX_GID env vars into supervisor container
- Update PVC init container securityContext with resolved UID/GID
  instead of hard-coded root
- Add comprehensive unit tests for resolution logic and annotation
  parsing (resolve_sandbox_uid, resolve_sandbox_gid, OpenShift SCC
  annotation parsing)

* feat(driver-vm): add configurable sandbox UID/GID and update docs/examples

Phase 4 of the numeric-UID plan: replace hardcoded SANDBOX_UID (10001)
in VM rootfs preparation with configurable sandbox_uid/sandbox_gid fields.

Changes:
- Add sandbox_uid/sandbox_gid to VmDriverConfig with serde derives
- Pass resolved UID/GID through prepare_sandbox_rootfs_from_image_root
  to ensure_sandbox_guest_user which writes /etc/passwd/group/gshadow
- Update BYOC Dockerfile: remove groupadd/useradd, document runtime UID
  injection and the ability to skip baked-in sandbox user
- Update gateway-config.mdx: document sandbox_uid/sandbox_gid for both
  Kubernetes (with OpenShift SCC autodetection) and VM drivers
- Update sandbox-compute-drivers.mdx: add Sandbox User Identity section
  explaining numeric UID support across all compute drivers
- Update rootfs tests to use non-default UIDs, verify config passthrough

* fix(supervisor): harden tests for restricted CI container environments

Guard tests against CI-specific constraints: root without CAP_SETPCAP,
UIDs with no /etc/passwd entry, and restricted /proc access.

Robert Sturla 48545cfb59 feat(sandbox): add GCE metadata emulator for Google Cloud (#1763)
* feat(core): add shared GCP constants module

Single source of truth for GCP naming: env var aliases, provider config
keys, token search order, and Vertex-specific env vars. Consumed by
openshell-server, openshell-providers, and openshell-sandbox.

- Add google_cloud.rs with metadata emulator host and loopback address
- Define PROJECT_ID, REGION, and SERVICE_ACCOUNT_EMAIL env var aliases
- Add provider config key constants for gcp provider implementations
- Define TOKEN_ENV_KEYS search order (SA token takes priority over ADC)
- Add Vertex-specific env vars for Goose and Claude Code SDK integration
- Add STATIC_CONFIG_KEYS as union of all alias arrays for env resolution
- Export module via openshell-core lib.rs

* feat(providers): add google-cloud and vertex provider plugins

Add GoogleCloudProvider and VertexProvider implementing inject_env to
project GCP config (project ID, region, SA email, metadata host) into
sandbox environment variables. Replace the inline Vertex AI env
injection in the server with the registry-based inject_env dispatch.

Also adds the google-cloud.yaml provider profile with SA JWT and ADC
OAuth2 credential refresh flows.

* feat(sandbox): add GCE metadata emulator for GCP

Add a loopback HTTP server on 127.0.0.1:8174 inside the sandbox
network namespace that emulates the GCE instance metadata API.
GCP client SDKs discover it via GCE_METADATA_HOST and obtain
credential placeholders that the proxy resolves to real tokens
at egress.

Add metadata_server module with MetadataHandler trait and
netns-aware TCP binding via std::thread (not spawn_blocking)
to avoid tokio pool namespace contamination
Add google_cloud_metadata module implementing the GCE metadata
API subset (token, project-id, email, scopes, service-accounts)
Add child_env_resolved() and gcp_token_response() to
ProviderCredentialState for GCP-aware credential projection
Wire metadata server into sandbox lifecycle before SSH handler
Collapse multi-line HTTP response format string into single line

* docs(sandbox): add GCP credentials documentation

flows, injected environment variables, metadata emulator behavior, and
network policy configuration for GCP APIs.

* feat(cli): support --from-gcloud-adc for google-cloud providers

Widen --from-gcloud-adc to accept google-cloud providers. The ADC
credential key is derived from the provider profile rather than
hardcoded per type, so future GCP provider types get ADC support by
declaring the right refresh metadata in their profile YAML.

Add ProviderTypeProfile::adc_credential() to find the ADC-compatible
credential from a profile's refresh metadata. Remove unused
VERTEX_AI_ADC_TOKEN_KEY and GCP_ADC_TOKEN_KEY constants.
