Blockly Collaboration WebSocket Server

This server handles real-time synchronization for the collaborative Blockly editor using Yjs.

How it works

• Built with Yjs for conflict-free real-time collaboration
• Uses WebSockets for efficient real-time communication
• Handles multiple rooms for separate collaboration spaces
