container_relations is a generic parent/child graph used by blog (menu_nodes), market (marketplaces), and events (calendars). Move it to cart as shared infrastructure. All services now call cart actions (attach-child/detach-child) instead of querying the table directly. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
