When daemon restarts, SESSION_HISTORY is lost because it's an in-memory
Map. This fix adds disk-based timeline loading from Codex rollout files.
Changes:
- Add loadPersistedHistoryFromDisk() method to load from rollout files
- Add helper functions for finding and parsing rollout JSONL files
- Call disk loading in connect() when resumeHandle exists but SESSION_HISTORY is empty
- Add E2E test for timeline persistence across daemon restart
The rollout files are stored at ~/.codex/sessions/<date>/rollout-*.jsonl
and contain JSONL entries with response_item and event_msg types.
