* Create frigate and go2rtc runtime users in the image * Add single fix-ownership helper for volume permission migration * Add init-usermod oneshot for PUID and PGID remapping * Chown newly created runtime directories to the frigate user * Run sentinel-guarded ownership sweep during prepare * Add host-side volume permission migration script * Guard log directory ownership for user-mode startup * Fall back to plain s6-log when running without root * Assert PUID remapping and sweep sentinel in CI smoke test * Skip the ownership sweep in the devcontainer * Pin FRIGATE_RUN_AS_ROOT in ownership tests * Do not record the sweep as complete when a chown failed * Validate PUID and PGID in the migration script * Treat a failed ownership scan as an incomplete sweep * Reject PUID and PGID of 0 during remapping * Handle symlinks, dry runs, and sentinel write failures in the sweep * Treat an absent sweep root as an incomplete sweep
