feat: Implement LiveCode module with WebSocket and SSE support

- Added config management using `useConfig` for environment variables.
- Created `LiveCode` class to manage WebSocket connections and routing.
- Implemented `SSEManager` for Server-Sent Events handling.
- Developed `WSSManager` for managing WebSocket connections with heartbeat functionality.
- Introduced `ReconnectingWebSocket` class for robust WebSocket client with automatic reconnection.
- Added test files for live application demonstrating WebSocket and TCP server integration.
