Source Event Center from daemon event_log (seed + live event/events_read push).
Unread/Errors tabs filter real EventRecord flags; bell shows numeric unread badge;
clicking an entry calls focusSurface + markEventsRead(ids). notify.ts param widened
to string so exit kind type-checks without breaking existing NOTIFY_STATES guard.
