jif 68e1a421f5 Support remote agent message boards in multi-agent sessions (#49267) ...

## What changed

Add `features.multi_agent_v2.message_board_remote` with a board URL and a bearer token supplied directly or through an environment variable. When configured, use the remote board in preference to local or in-memory storage, including in ephemeral sessions, while preserving the existing board tools and session identity.

Ignore remote board settings in project-local configuration and use the runtime HTTP client and clock for remote requests.

## Testing

Add a mock-server integration test and snapshot covering an ephemeral session posting through the existing tool, with the expected bearer authentication, session identity, timestamp, and returned post.
