Trust moat: completion gates now fail CLOSED

• Fail-closed completion gates (autonomy/run.sh): each completion gate was
  armed as type <gate_fn> && ! <gate_fn>, so if the council library failed to
  source, the type probe was false and the gate was silently skipped - a
  completion claim could then reach the accept branch UNVERIFIED (a fake-green).
  The gate chain now verifies the core gate functions are loadable before running;
  if any is missing, the completion claim is refused and the loop keeps iterating
  rather than passing ungated. Never fires in a healthy install (functions are
  sourced); only triggers on a genuinely broken/partial load, exactly when
  failing open is unsafe. Found by the cycle-3 adversarial bug-hunt.
