/**
 * Job status endpoint (contracts.ts "THE ASYNC PROTOCOL" §4): the chat

 * announcement (the store emits post-write, debounced client-side), and
 * on channel resync (push-architecture S4, 2026-10-02 — the old interval
 * poll is retired). It drives the dispatch cards, the sub-agents panel,
 * and the re-sync when a job settles. `turnInFlight` rides along for the
 * settle logic's idle check.
