3.7 — Live sync animation (mock, GREEN)

Phase: 3 — Delivery Tree (Surface E) Stage: GREEN

Depends on: 2.5, 3.6

• Live sync animation OutOfSync -> Syncing -> Synced driven by /api/stream delivery event type (add this event type alongside the existing topology one)

Mock only: /api/stream emits synthetic deltas, not a real Argo Application watch. See REQUIREMENTS.md.

Verify

curl -N http://localhost:3000/api/stream   # observe delivery events once event type is added
