Ensure AI-merge clean-room directories are cleaned up even when setup fails before worktree registration.
- Move clean-room directory creation inside the cleanup guard so terminal setup failures can remove it.
- Skip cleanup only when no merge root was ever created, while still unregistering any registered paths.
- Add regression coverage for active-session registration failure after mkdtemp and before git worktree add.
