Workflow pack for Recued-sent Intercom customer replies. It composes the Intercom capability pack with a closure ledger: send one public admin comment through the existing Intercom approval gate, persist only the connection/conversation reply-watch linkage in data.shared, and let a scheduled watcher re-read that exact conversation until Intercom reports a configured closure state or a customer-waiting owner-review signal after the Recued reply. This pack does not replace Intercom Workflows, Rules, snooze/reopen/close automation, assignment/routing, SLAs, native notifications, webhooks, or teammate workflows; it adds Recued-visible closure state for conversations Recued replied to.
