feat(activity): repo-scoped automation review CLI (WP-0028)

Ship the activity console script for consumer-repo morning review: list,
status, runs, deliverables, inbox, checkpoint, and ack. Offline-first with
git + local defs; enriches from ops API and State Hub. Multi-source trust
matrix never reports did-not-run when git has the artefact. Adds
target_repo filter on GET /ops/automations.
