Brent Traut c92700d299 Backfill exec completion items through paginated history (#57800) ...

## Why

`codex exec` recovers turn items at completion because item notifications can be dropped under backpressure. This recovery needs to respect the thread's history mode.

## What changed

For paginated threads, fetch every page from `thread/items/list`, scoped to the completed turn. Preserve items already present in the completion notification when merging the recovered history, and stop recovery if a cursor repeats. Keep `thread/read` recovery for other history modes.

## Testing

Add regression coverage for recovering a final answer across multiple item pages and for a failed fork recovering only its own turn.
