feat(message): implement version-based incremental sync and WS compression

Implement a more efficient conversation synchronization mechanism using
version numbers instead of sequence numbers to reduce bandwidth usage.
This includes adding support for Gzip decompression on WebSocket
messages to optimize data transfer.

- Add `pako` for WebSocket message decompression
- Implement `getSyncByVersion` in `MessageService`
- Implement `syncByVersion` in `MessageSyncService` to handle incremental
  updates and conversation state changes
- Update `WebSocketService` to support binary frames and Gzip inflation
- Add `syncVersion` to `MessageStore` for tracking synchronization state
