Surfaces the clarification loop over the wire: ServerMessage.ClarificationRequired
(clarification.required, carrying the structured questions) is mapped from
ClarificationRequestedEvent; ClientMessage.ClarificationResponse carries the
operator's answers and is routed to orchestrator.submitClarification on both
the global and session streams. Reuses the core ClarificationQuestion/Answer
types as the wire shape. Round-trip tests for both directions.
