    - GET /state: Get current environment state
    - GET /schema: Get action/observation schemas
    - WS /ws: WebSocket endpoint for persistent sessions

Usage:
    # Development:
    uvicorn server.app:app --reload --host 0.0.0.0 --port 7860

    # Or run directly:
    python -m swebench_in.server.app
