Workflow pack for Recued-created Linear issue comments. It composes the Linear capability pack with a closure ledger: add one owner-approved Markdown comment to an existing Linear issue, persist only the connection/issue/comment linkage in data.shared, and let a scheduled watcher re-read that exact issue until Linear reports it completed or canceled. This pack does not replace Linear comments, native notifications, issue workflow states, project views, reminders, roadmaps, or general issue reporting; it adds Recued-visible closure state for issue comments Recued created.
