chiam-oai 772abc9425 Preserve and expose thread item lifecycle timestamps (#47114) ...

## What changed

- Persist producer-recorded item start and completion times in thread history, preserving existing non-null values on updates.
- Return nullable `startedAtMs` and `completedAtMs` Unix millisecond timestamps from `thread/items/list`, and update the generated schemas and TypeScript and Python types.
- Leave timestamps unknown for existing rows and older writers.

## Testing

Add coverage for exact timestamp persistence, protocol round trips with present and missing timestamps, paginated item responses, and compatibility with older database writers.
