Cards say when their agent waits for a restart

When Obeya is about to restart because new code landed, it waits for busy agents, and agents that end a turn meanwhile pause until the restart. A card approved in that window used to read “Done · agent working” although its agent had already said nothing was left. Now such a card reads “Done · agent waits for restart” in muted ink, and its hint explains that the agent finishes what is left once Obeya runs again; a card in progress whose agent paused reads “Agent waits for restart”.
