🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Bound timeout diagnostics before rejecting.

Line 63 waits for diagnostics before runBitsocialCommand rejects. collectDaemonDiagnostics reads each complete log file at Line 119 and truncates it only afterward. A large or slow log can therefore delay the rejection until Vitest’s 30-second or 60-second timeout fires, losing the intended diagnostics. Read only a bounded tail and add a bounded fallback before awaiting diagnostics.

Also applies to: 119-119

collectDaemonDiagnostics and collectTimeoutDiagnostics so diagnostic reads use
only a bounded tail of each log file, with a bounded fallback available before
awaiting collection. Ensure runBitsocialCommand rejection is not delayed by
large or slow logs and preserves the existing failure-diagnostic message when
collection cannot complete.

Add a timeout-race regression test.

Add focused coverage for runBitsocialCommand: keep the child alive past timeoutMs, provide delayed diagnostics, emit output larger than tailOf’s limit, and assert the rejection includes the truncated output and diagnostics. Assert that the later close event cannot resolve the promise. No equivalent coverage exists.
