/**
 * Gallery Cleanup - applies virtual changes to the real filesystem:
 *   1. Deletes photos hidden for more than 30 days (source + thumbnail + fullsize)
 *   2. Renames folders on disk to match _displayName from data.json
 *
 * Run manually: php cleanup.php          (dry run - only shows what would happen)
 *               php cleanup.php --apply  (actually deletes and renames)
 * After running with --apply, trigger a crawler update so it refreshes data.json.
