--install-service now registers the service under
NT SERVICE\gpu-turnstile (low-privilege, per-service, no password) and
grants it modify access to the install dir (for self-updates) and the
LOG_FILE dir, plus read access to an external config file. Grants run
after CreateService because the virtual account's SID does not exist
before registration; a failed grant rolls back the registration.
