Owen Lin b1373b74a2 Add durable reverts for paginated threads (#38292) ...

## What changed

- Add `ThreadStore::revert_thread` to retain history before a selected turn by creating a new immutable rollout and atomically switching the thread's stored rollout path.
- Preserve the logical thread ID and session metadata across repeated reverts.
- Track every rollout owned by a thread so archive, unarchive, and delete operations handle the complete lineage and restore moved files when metadata updates fail.
- Prevent deletion when forks still reference any rollout in the thread's lineage.

## Testing

- Cover repeated reverts, compressed source rollouts, lifecycle operations over reverted histories, reference-aware deletion, and cross-process unarchive locking.
