Three independent fixes for worker daemon instability:
1. Remove version mismatch auto-restart from ensureWorkerStarted() (#1435).
The marketplace bundle ships with __DEFAULT_PACKAGE_VERSION__ unbaked,
causing BUILT_IN_VERSION to fall back to "development". This creates a
100% reproducible mismatch on every hook call, killing a healthy worker
and often failing to restart. Same pattern across #566, #665, #667,
#669, #689, #1124, #1145 (8+ releases).
2. Add process.ppid and PID-file PID to aggressiveStartupCleanup()
exclusions (#1426). Without this, a newly spawned daemon SIGKILLs
the hook process that spawned it and any already-running worker
the PID file points to.
3. Increase POST_SPAWN_WAIT from 5s to 15s (#1423). The 5s timeout was
sized for Linux (<1s startup) but macOS ARM64 cold starts take 6-8s
with Chroma enabled.
