/**
 * Directly write a single artwork into the Meilisearch index, bypassing the queue.
 *
 * Useful when:
 *   - A rebuild was run but the queue worker was not consuming the `search` queue.
 *   - A specific artwork is missing from the live index and you want it visible immediately.
 *   - You need to force-push a corrected document after schema changes.
 *
 * Usage:
 *   php artisan artworks:search-force-index 69810
 *   php artisan artworks:search-force-index          # interactive prompt
 *   php artisan artworks:search-force-index 69810 --dry-run
 *   php artisan artworks:search-force-index 69810 --force  # index even if not public/approved/published
