Owen Lin af7f6f4d34 Include item start times in completion events (#35363) ...

## What changed

- Add an optional `started_at_ms` field to `ItemCompletedEvent`, retaining
  compatibility with older persisted events that lack it.
- Track the first start timestamp for each in-flight item and attach it when
  emitting and persisting the completion event. If no start was recorded, use
  the completion timestamp as a fallback.
- Emit a complete start/completion lifecycle for subagent activity items.

## Testing

- Cover concurrent item timing, repeated starts, turn-boundary cleanup, the
  missing-start fallback, subagent activity, and persisted web-search events.
