Tests cover timeout clamping, delayed discovery, failure propagation, and cleanup. A standalone script validates replacement behavior. ChangesStale daemon replacement
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: ⚪ Minimal · up to The client now uses bounded stale-daemon discovery and termination timeouts, retains typed diagnostics, and adds cleanup and regression coverage.

In `@packages/client/src/client.test.ts`:
- Line 353: Extend the declared result type used by the
LifecycleInternals.runCommand test double to include optional timedOut and
commandError fields, so existing mockResolvedValue calls type-check while
preserving current behavior.
In `@packages/client/src/client.ts`:
- Line 511: Clamp the stale-daemon termination deadline in the ensureReady flow
instead of using startTimeoutMs directly. Use a dedicated configurable
termination timeout constrained to the required 5–10 second range, ensuring
finite behavior even when startTimeoutMs is oversized or infinite, while
preserving the existing termination and replacement flow.
