Lets orchestrators (e.g. an account-management service provisioning a Hermes VPS) seed an OAuth refresh credential non-interactively instead of walking the user through `hermes setup` + the device-flow login dance. Matches the existing first-boot-only pattern used for .env, config.yaml, and SOUL.md. If HERMES_AUTH_JSON_BOOTSTRAP is set and $HERMES_HOME/auth.json doesn't already exist, write the env var's contents to auth.json with mode 600. The `[ ! -f ... ]` guard is critical: it ensures that on container restart the rotated refresh token Hermes wrote back to the persistent volume is never clobbered by the now-stale value the orchestrator originally seeded. Generic name (not Nous-specific) so the feature is reusable by any future orchestrator.
