feat: add worktree cleanup audit integrity (Closes #404)

Reconcile before/after branches/ snapshots so preserved worktrees cannot
disappear without removal logs or explained state transitions.

- worktree_cleanup_audit.py: snapshot capture, disposition reconciliation
- gitea_capture_branches_worktree_snapshot, gitea_assess_worktree_cleanup_integrity
- Final-report rule author.worktree_cleanup_audit_proof
- worktree-cleanup.md bulk audit section
- tests/test_worktree_cleanup_audit.py (11 cases)

"""Worktree cleanup audit integrity and reconciliation (#404).
Captures before/after snapshots of ``branches/`` directories and registered
worktrees, reconciles every initial path to exactly one disposition, and fails
closed when preserved worktrees disappear without an explicit removal record.
