When a polecat runs gt done, the worktree is removed but the parent
polecat directory could be left behind containing only .beads/. This
caused gt polecat list to show ghost entries since exists() checks
if the polecatDir exists.
The fix adds explicit cleanup of .beads/ directories:
1. After git worktree remove succeeds, clean up any leftover .beads/
in the clonePath that was not fully removed
2. For new structure polecats, also clean up any .beads/ at the
polecatDir level before trying to remove the parent directory
