Workflow pack for Recued-sent Canva comment replies. It composes the Canva capability pack with a closure ledger: reply once to an existing Canva preview comment thread through the existing approval gate, persist only the connection/design/thread/reply linkage in data.shared, and let a scheduled watcher re-read that exact thread until Canva reports it resolved. This pack does not replace Canva comments, native notifications, comment resolution, design review dashboards, webhook administration, or general design status reporting; it adds Recued-visible closure state for comment replies Recued sent.
