- Refactor HealthDaemon to use a tracked session (AbortController + awaitable
promise) instead of fire-and-forget health check loops, preventing health
checks from running after a service is stopped
- Stop health checks before terminating daemon to avoid false crash reports
during intentional shutdown
- Guard onExit callbacks with AbortSignal to prevent stale session callbacks
- Add logErrorOnce utility to deduplicate repeated error logging
- Fix SystemForEmbassy.stop() to capture clean promise before deleting ref
- Treat SIGTERM (signal 15) as successful exit in subcontainer sync
- Fix asError to return original Error instead of wrapping in new Error
- Remove unused ExtendedVersion import from Backups.ts
