After writing the updated script, _stop_event.set() caused a clean exit
(code 0). SCM failure recovery only fires on non-zero exit, so the service
stayed down permanently after every auto-update.
Fix: set _update_restart=True before signalling stop; SvcDoRun() checks
the flag after main() returns and calls sys.exit(1), which triggers the
sc.exe failure recovery chain (restart/5s/10s/30s configured at install).
Replace the scheduled-task approach (required user to stay logged in) with a
proper Windows Service using pywin32. The service runs as LocalSystem, starts
at boot, and auto-restarts on failure — no PowerShell window needed.
Agent changes (jarvis-agent-windows.py):
- Add Windows Service class via pywin32 (JarvisAgentService)
- Cleanly handles SvcStop by setting a threading.Event
- main() loop uses _stop_event.wait() instead of time.sleep() so stop is immediate
- self_update() signals the stop event when running as a service (SCM restarts it)
- __main__ block dispatches to SCM entry point or HandleCommandLine (install/stop/remove)
- Falls back to direct run if pywin32 not installed (for debugging)
Installer changes (install-windows.ps1):
- pip install pywin32 + postinstall (registers service runner DLLs)
- Python search prefers system-wide install (accessible by LocalSystem)
- Downloads Python 3.11 directly from python.org for Win 8.1 machines without winget
- Removes legacy JARVIS-Agent scheduled task if present
- Registers JARVISAgent service with --startup auto
- Configures sc.exe failure recovery (restart at 5s/10s/30s)
- Updated management commands in summary (Start-Service, Stop-Service, etc.)
