eknight-oai 06971ec9aa Prevent message-board notifications from reopening final answers (#48982) ...

## Why

Message-board notifications delivered as ordinary injected input could cause an agent to sample again after its final answer.

## What changed

Route notifications through the current turn's mailbox as `InterAgentCommunication`, checking atomically that the turn is running and still accepts mailbox delivery. Skip notifications when delivery is closed. Accepted notifications may remain in conversation history for a later turn without reopening the finalized answer or starting a new turn.

Report pending inter-agent communications as mailbox activity, while preserving priority for steering input.

## Testing

Add regression scenarios for notifications arriving before and after finalization, asserting no extra sampling and the expected notification presence in the next turn. Extend input-queue coverage to recognize already-pending mailbox activity.
