feat(max-bot): implement mock-based message flow with WIP file queue

- MAX API integration (long polling)
- MockPlatformClient for agent simulation
- File download & workspace storage
- Basic commands: /help, /start
- Attachment queue: add works, list/remove need testing

[WIP: attachment queue commands]
[MOCK-ONLY: requires real agent for production]
