Owen Lin bcdc695877 Track inherited paginated rollout prefixes (#33930) ...

## What changed

- Add `HistoryPosition` to identify a source thread and an exclusive rollout
  prefix by ordinal and JSONL byte offset.
- Add optional `history_base` metadata to `SessionMeta` so a thread can record
  an inherited prefix of another paginated rollout.
- Default missing `history_base` metadata to `None` and omit it when unset to
  preserve compatibility with existing rollout metadata.

## Testing

- Verify that legacy session metadata without `history_base` deserializes with
  no inherited history position.
