jif f05aa41da6 Route message-board notifications through agent mailboxes (#59139) ...

## Why

Board notifications were skipped when recipients had no active turn accepting mailbox delivery. Queue them through the ordinary agent-message path so idle recipients can receive them in a later turn.

## What changed

- Submit board notices as `Op::InterAgentCommunication` with `trigger_turn` disabled, preserving normal mailbox scheduling without reopening finalized answers.
- Hold a residency guard through dispatch of submitted agent messages to coordinate delivery with agent eviction.
- Update board tool descriptions to describe the host's notification queueing and wake policy.

## Testing

Update local and HTTP board scenarios to cover queued idle notices, delivery after a finalized answer, and mailbox delivery before a pending tool call. Extend residency coverage to verify that submission waits for the eviction gate and queued messages survive eviction.
