guinness-oai 64c9cde458 Record realtime conversation history in Core (#41924) ...

## Why

Realtime history should be recorded consistently for every Core host, including
when no app-server event listener is attached.

## What changed

- Move transcript segmentation, session boundaries, and backing-agent artifact
  promotion into Core for paginated threads.
- Persist canonical realtime items through the thread store in event order and
  emit dedicated history lifecycle events for hosts to present.
- Translate those Core events into the existing app-server realtime item
  notifications without app-server persisting the items a second time.

## Testing

- Cover Core-only persistence across repeated sessions, ephemeral sessions,
  accepted and rejected steering, typed input ordering, and artifact promotion.
- Verify app-server notifications correspond to the persisted timeline.
