+Re-running install on an already-registered service converges instead of
+failing: a running service is stopped first, the installed binary copy is
+refreshed only when the content differs, the registration (Windows service
+config / systemd unit) is updated only where it drifted, and the service is
+started again only if it was running before.

 `%ProgramData%\gpu-turnstile\` for logs; Linux: `/var/lib/gpu-turnstile/`
