jif 9c23d93d5b Add opt-in MCP discovery for in-memory agent message boards (#58973) ...

## What changed

Enable `multi_agent_v2` and the new `agent_message_board_mcp` feature to automatically start a temporary, tree-scoped HTTP MCP message board without plugin or endpoint configuration. The MCP feature defaults off and takes precedence over `agent_message_board`.

Share board state across parent and child agents while retaining each caller's host binding. Keep the server alive while participating threads remain, and serialize board tool calls through the MCP server configuration.

## Testing

Extend the HTTP board integration scenario to cover automatic discovery, parent-child message sharing, child subscriptions and posts after the parent unloads, serialized mutations, and absence of a persistent board database.
