Release v0.8.2

Fixed

• Add event loop watchdog that detects zombie state (asyncio loop closed but process alive) and force-exits, allowing start.sh auto-restart to recover
• Enable launchd KeepAlive so the service auto-restarts even if start.sh itself exits (e.g. rapid crash limit)

Changed

• Enhanced --status command to detect inactive bots via log mtime checking, reporting detailed diagnostics instead of a misleading "running" status
