fix(issue-36): a job that cannot be registered after a rebuttal ends the loop with rc 1

Review of f5cadd9 (planner-reviewer-codex-01, R1): the compliance job's
registration failure was only logged, so a passing next round ended the
real loop process with rc 0. Compliance now returns 1 when it cannot be
registered or does not finish, as the correction step already does.
Re-adjudication and arbitration also return 1 when their job cannot be
registered; a registered job that yields no verdict keeps the designed
fail-closed fallback.

S4c (stubbed delegate_job, a fixture whose later rounds never pass) is
replaced by S3c: a real `python -m lib_py.loop` process whose wrapper runs
an executable that simulates the agents, refusing the compliance,
re-adjudication or arbitration registration while the next round passes.
