sayan-oai 18f50c9e62 Track model and personality in world state (#35530) ...

## What changed

- Add model and personality sections to the persisted world-state snapshot.
- Generate model-switch and personality instructions through world-state diffs, including when prior state must be inferred during replay.
- Keep those instruction fragments in standalone developer messages instead of merging them with adjacent context updates.

## Testing

- Cover initial, unchanged, and changed model and personality states.
- Verify that model changes are recorded in rollout world-state items.
