Add resource_version-based optimistic concurrency control to the
persistence layer. Every write now requires an explicit WriteCondition
(MustCreate or MatchResourceVersion), enforced at compile time by
gating unconditional put/put_message behind #[cfg(test)].
- Add WriteCondition enum and put_if for conditional writes
- Add update_message_cas for atomic read-modify-write operations
- Add list_messages/list_messages_with_selector helpers that hydrate
resource_version from authoritative DB rows
- Convert all production write paths to CAS-aware methods
- Gate put/put_message behind #[cfg(test)] to prevent non-CAS writes
- Use structured PersistenceError::UniqueViolation matching instead of
string matching for duplicate detection
- Hydrate resource_version from WriteResult directly on creates,
eliminating unnecessary read-after-write round trips

* feat(exec): add bidirectional streaming for interactive TTY sessions
The existing ExecSandbox RPC sends stdin upfront in the request body,
making interactive programs (bash, top, vim) unusable with --tty. This
adds an ExecSandboxInteractive bidirectional streaming RPC that forwards
live keystrokes, terminal resize events, and EOF to the sandbox.
- Add ExecSandboxInteractive RPC, ExecSandboxInput and
ExecSandboxWindowResize messages to the proto definition
- Implement server handler with relay bridging, PTY allocation via
russh channel.split(), and timeout support
- Implement CLI client with raw mode, spawn_blocking stdin reader,
SIGWINCH resize forwarding, and process::exit for clean shutdown
- Route to interactive path only when --tty is explicitly passed

* fix(exec): address interactive TTY streaming review feedback
Server-side (sandbox.rs):
- Close SSH channel after EOF so PTY-backed programs (bash, vim, top)
terminate on client disconnect instead of leaking the session
- Break output loop when tx.send() fails (client gone) to tear down
the streaming pipeline promptly
- Default zero cols/rows to 80x24 before request_pty, matching the
proto "0 = use default" contract and preventing 1x1 terminals for
non-CLI clients
Client-side (run.rs):
- Replace spawn_blocking stdin reader with a detached std::thread so
the tokio runtime shutdown does not hang on a thread blocked in
stdin.read(). This removes the need for std::process::exit(),
allowing save_last_sandbox() in the caller to execute normally
- Switch from futures::channel::mpsc with try_send() to
tokio::sync::mpsc with blocking_send() for proper backpressure —
try_send silently stopped forwarding all input when the channel
filled during paste or slow network
- Add TaskGuard (abort-on-drop) for the resize task to ensure cleanup
on all return paths including early errors

Consolidate shared constants and helpers into openshell-core to avoid
duplicate definitions scattered across crates. Adds OPENSHELL_SANDBOX
to the sandbox_env module so all drivers and the sandbox supervisor
reference it via a typed constant rather than string literals, matching
the existing pattern for SANDBOX_ID, ENDPOINT, and the other env vars.
Allow CLI to connect to gateways with self-signed or untrusted
certificates by skipping TLS verification when --gateway-insecure
is set via flag or OPENSHELL_GATEWAY_INSECURE env var.

* feat(cli): Allow printing only the policy when retrieving sandbox info
* feat(cli): Indicate policy source and revision when retrieving sandboxes
* cargo fmt
* feat(sandbox): add gpu sandbox scheduling support
Allow sandbox creation to request GPU resources explicitly or infer them from GPU image names. This wires GPU intent through bootstrap, validates gateway support, and adds dedicated GPU E2E coverage for follow-up cluster testing.
