chengyongru 6daf91c620 feat(mailbox): add multi-agent mailbox channel plugin ...

File-system-based mailbox channel for inter-agent communication.
Zero modifications to existing code — pure channel plugin.

- MailboxManager: atomic file I/O, registry CRUD, message send/poll
- MailboxConfig: Pydantic config with camelCase aliasing
- MailboxChannel: polls inbox, routes messages via bus, callback routing
- Anti-loop protection: TTL decrement + circular trace detection
- allowFrom access control inherited from BaseChannel
- 29 unit/integration tests + standalone smoke test script
