The R1 grace after a subscriber idle timeout only asked herdr whether the agent was still `working`. herdr never reports that for codex, so a codex review longer than the idle timeout was closed as deadline_timeout mid-turn and its eventual `completed` refused - the same status blindness behind the agent_blocked misjudgement. `_agent_still_working` now also accepts the pane's own busy token, the evidence send_keys_safe already uses to confirm delivery. Adds a wrapper test where a codex-like agent (idle per herdr, busy per pane) idles out the subscriber and completes out of band afterwards.
