fix(tests): skip maint subprocesses in singleton-lock test
test_supervisor_singleton_lock_acquired called mod.main() which, since
ec004821, runs run_pending_tasks() before start_callosum_in_process.
On a fresh tmp_path, every maint script is pending, so main() spawned
12 subprocesses (~1.5-2s under coverage) before reaching the stub that
raises SystemExit(0). Under system load that overruns the 5s default
pytest-timeout, producing the intermittent FAILED seen during full-suite
runs. Monkeypatch run_pending_tasks to a no-op — the test is about
flock acquisition, not migrations.
Verified with 10 consecutive `make test` runs, all green.
