The status snapshot (.agenthub/status/latest.md) was only refreshed on an
explicit `status --update`, so it drifted stale and misled agents that
follow golden rule #2 ("read status/latest.md") — e.g. an implementer
seeing an old task list and picking the wrong task.
- src/server/statusRefresh.ts: subscribe to the event bus and regenerate
the snapshot on every task/handoff/decision/memory change (REST and
filesystem-watch paths), debounced 300 ms. Presence ('agent') events
are skipped; the snapshot lives outside the watched dirs so it can't
feed back into the watcher.
- wired into startServer lifecycle (start + stop on close).
- test: status/latest.md reflects a new task shortly after POST /tasks.
117/117 green.
Bump 0.3.0 -> 0.3.1.
