/**
 * PublishScheduledArtworksCommand
 *
 * Runs every minute (via Kernel schedule).
 * Finds artworks with:
 *   - artwork_status = 'scheduled'
 *   - publish_at <= now() (UTC)
 *   - is_approved = true (respect moderation gate)
 *
 * Publishes each one:
 *   - sets is_public = true
 *   - sets published_at = now()
 *   - sets artwork_status = 'published'
 *   - dispatches Meilisearch reindex (via Scout)
 *   - records activity event
 *
 * Safe to run concurrently (DB row lock prevents double-publish).
