Owen Lin 8d6a91b1ff Preserve item timestamps in thread history projections (#35689) ...

## What changed

- Add optional start and completion timestamps to `ThreadHistoryItemChange`.
- Populate them from canonical `ItemCompleted` records during stateless thread history projection.
- Treat a zero completion timestamp as absent, and leave timestamps unset for legacy builder events that do not provide them.

## Testing

- Cover projected item timestamps, including missing start times and zero completion times.
