New file tests/test_issue57_logs_follow_registry.py: the resolver (L1),
registry.py (L2), the wrapper's submit/wait/logs (L3), publish_event.py
(L4), control_plane.from_env, worktree_prepare, status.sh, the comment-5
disk fallback, and the invariant that an explicit DELEGATE_JOB_LOGS_DIR
still wins. Every test ends by asserting the workspace's own
.mam/delegate_job_logs was never created.
Two existing tests gain monkeypatch.delenv("MAM_JOBS_DIR"): conftest's
autouse _isolate_mam_state_dirs gives every test a MAM_JOBS_DIR, and under
the sibling rule the WORKSPACE_ROOT/cwd fallbacks they assert would
otherwise resolve next to that registry. The order they assert (explicit
root, workspace, cwd) is unchanged.
