feat(tcp_connection): add MessagePack serialization support

- Add rmp-serde dependency for MessagePack serialization
- Implement write_msgpack and read_msgpack methods for basic MessagePack support
- Add write_large_msgpack and read_large_msgpack methods for chunked transmission
- Add error conversions for rmp-serde errors
- Add comprehensive tests for MessagePack functionality
- Fix code formatting and improve readability
- Make stream field pub(crate) for better access control

All tests pass successfully, ensuring backward compatibility.
