The /_ws_tunnel endpoint pipes a WebSocket into the full gRPC service. On a
plaintext loopback gateway any web page could open it, since browsers do not
apply CORS to WebSocket upgrades. Mount the tunnel only when
enable_websocket_tunnel is set (config file, --enable-websocket-tunnel, or
OPENSHELL_ENABLE_WEBSOCKET_TUNNEL; server.enableWebsocketTunnel in Helm).
BREAKING CHANGE: gateways behind an authenticating edge proxy must set
enable_websocket_tunnel = true for CLI edge-tunnel connections.

* feat(gateway): add readiness probe metrics and test-only store close
Emit Prometheus readiness metrics for database probes (healthy gauge and
outcome-labeled latency histogram) with coverage in health HTTP tests.
Restrict Store::close behind test support cfg to prevent accidental runtime
pool shutdown under live traffic.

* feat(server): add Prometheus metrics infrastructure and gRPC/HTTP request metrics
Add metrics exposition via a dedicated server port (--metrics-port,
default disabled) following the same optional-listener pattern as the
health port. The metrics crate facade records counters and histograms
in the MultiplexedService hot path, and a PrometheusHandle renders them
at GET /metrics on the dedicated port.
Metrics added:
- openshell_server_grpc_requests_total (counter: method, code)
- openshell_server_grpc_request_duration_seconds (histogram: method, code)
- openshell_server_http_requests_total (counter: path, status)
- openshell_server_http_request_duration_seconds (histogram: path, status)
* feat(helm): add metrics port to openshell-server helm chart
Expose the Prometheus metrics endpoint in the helm chart by adding
service.metricsPort (default 9090) to values, the --metrics-port arg
and container port to the statefulset, and a metrics service port.
Set metricsPort to 0 to disable.
Move /health, /healthz, and /readyz to a dedicated plaintext HTTP port
(default 8081) so Kubernetes probes work without mTLS client certificates.
- Add health_bind_address to Config with --health-port CLI arg
- Spawn standalone axum::serve for health_router on the health port
- Remove health routes from the main multiplexed HTTP router
- Update Helm statefulset probes from tcpSocket to httpGet on health port
- Fix cluster-healthcheck.sh to open/close TCP without sending data,
avoiding InvalidContentType TLS errors in the gateway log
Compute version strings from git describe in openshell-core's build.rs
using the guess-next-dev scheme (e.g. 0.0.4-dev.6+g2bf9969). All binary
crates and the TUI splash screen now use the shared openshell_core::VERSION
constant instead of CARGO_PKG_VERSION.
In Docker/CI builds where .git is absent, falls back to CARGO_PKG_VERSION
which is already set correctly by the sed-patch pipeline. Also adds
OPENSHELL_CARGO_VERSION support to the cluster image and fast-deploy
supervisor builds for parity with the gateway.
