jif a113f3e063 Consolidate Guardian reviewer lifecycle ownership (#45672) ...

## What changed

- Use cancellation guards to tie reusable reviewers and temporary forks to their lifetimes, including when a review future is dropped. Replace cancelled reusable reviewers before reuse.
- Share `ReviewerTasks` between the pool and `ThreadManager`, and wait for tracked cleanup during pool shutdown. Remove the separate session shutdown protocol.
- Move denial cleanup from core task handling into Guardian's turn start, stop, and abort hooks. Expose `install_reviewer` to register both thread and turn lifecycle contributors together.

## Testing

Add an integration test that exercises stale denial cleanup at turn start, completion, and interruption, including starting another turn after interruption.
