feat: Implement networking and collaboration features for z3ed

- Introduced a comprehensive networking system for real-time collaboration across the yaze app, z3ed CLI, and yaze-server using WebSocket.
- Added `WebSocketClient` and `CollaborationService` classes to manage connections, session hosting, proposal submissions, and automatic ROM synchronization.
- Enhanced the z3ed CLI with commands for connecting to the server, submitting proposals, and checking approval statuses.
- Updated documentation to include detailed usage instructions for the new networking features and collaboration workflows.
- Improved CMake configuration to support necessary libraries for networking, including JSON and OpenSSL.
