Workflow pack for Recued-sent Adobe Sign agreements. It composes the Adobe Sign capability pack with a closure ledger: create one agreement through the existing Adobe Sign approval gate, persist only the agreement/library-document/workflow linkage in data.shared when the agreement is sent with IN_PROCESS, and let a scheduled watcher re-read that exact agreement until Adobe Sign reports a role-specific completion status such as signed/approved/delivered/accepted/form_filled, or an exception status such as aborted/cancelled/expired/archived. This pack does not duplicate Adobe Sign reminders, participant notifications, expiration settings, webhook administration, agreement status dashboards, cancellation flows, or MegaSign/bulk sends; it adds Recued-visible closure state for agreements Recued sent.
