Fix Windows agent: exit(1) after self-update so SCM restarts the service

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).
