Phase 4 of local-only polecat branches: Handle conflict resolution edge case.
Problem: If polecat worktree is nuked before MR merges, the local branch
is gone and conflict resolution can't access it.
Solution: Witness now defers cleanup for polecats with pending MRs:
- HandlePolecatDone creates a cleanup wisp with "merge-requested" state
- Polecat worktree preserved until MERGED signal arrives
- HandleMerged then nukes the polecat (existing behavior)
Also updated mol-polecat-conflict-resolve.formula.toml:
- Removed fetch from origin (branches are local-only now)
- Added instructions to fetch from source polecat's worktree
- Added rig and source_polecat variables
