vouch-followuplisted

# /vouch-followup File "$ARGUMENTS" as a `followup` page proposal — a commitment with a due date that `vouch digest` lists until it's closed. Requires the company-brain page kinds (`vouch init --template company-brain`). Steps: 1. Extract what's owed, by whom, and when. If no due date is stated, ask — an undated followup never surfaces. 2. Call `kb_propose_page` with `page_type: "followup"`, a short imperative title, and `metadata`: `due_at` (ISO date), `followup_status: "open"`, `owner` when known. Put context in the body; cite a source id if the commitment came from a registered conversation or document. 3. To close or move one later: re-propose the same page (`slug_hint: <page id>`) with `followup_status: "done"` (or a new `due_at`) — status changes go through the gate like any other edit. 4. Report the proposal id and the due date filed. Never call `kb_approve`.
