e4d4319 deprecated the allowedWorktrees whitelist (git worktree registry +
same common-dir checks replace it) but left 4 tests asserting the old
contract:
- test_ack_skill: template must NOT contain allowedWorktrees: anymore,
only the deprecation comment
- test_ack_worker_profiles: legacy allowlist field is tolerated (no
'requires at least one path'); receipt no longer validated against it
- test_ack_launch_worker: capture_worktree_identity dropped the
allowlist arg; assert registered-worktree pass, symlink impostor and
unregistered-rejection under the new signature
