  enableWebSocket: true,    // ✅ WebSocket support
  enableGrpc: true,         // ✅ gRPC support  
  enableHttp2: true,        // ✅ HTTP/2 support

✨ NEW FEATURES

1. Multi-Protocol Support

✅ HTTP/HTTPS: Full HTTP/1.1, HTTP/2, HTTP/3 support
✅ WebSocket: RFC 6455 compliant with secure handshake
✅ gRPC: gRPC over HTTP/2 with message framing
✅ Custom Protocols: Extensible engine registration system

2. Protocol Engine API

// Register custom protocol engines
app.registerProtocolEngine('mqtt', {
  detect: (req) => req.headers['protocol'] === 'mqtt',
  parse: async (req) => ({ topic, payload }),
  validate: async (ctx) => true
});

// Enable/disable protocols dynamically
app.enableProtocol('websocket', { pingInterval: 30000 });
app.disableProtocol('grpc');

3. Cross-Protocol Authentication

// Same keypoint works across all protocols
const keypoint = {
  keyId: 'client_123',
  scopes: ['read', 'write'],
  protocols: ['https', 'wss', 'grpc+tls'] // Multi-protocol
};

// Authentication works for:
// - HTTP requests
// - WebSocket connections  
// - gRPC streams
// - Custom protocol handlers

4. Protocol-Aware Routing

// Route based on protocol
app.get('/api/data', (ctx) => {
  if (ctx.protocol === 'wss') {
    // WebSocket-specific response
    return ctx.json({ format: 'ws', data: [...] });
  } else if (ctx.protocol.startsWith('grpc')) {
    // gRPC-specific response
    return { message: grpcResponse };
  }
  // Default HTTP response
  return ctx.json({ data: [...] });
});

5. Enhanced Security Features

✅ Trusted Proxy Validation: Secure X-Forwarded-* headers
✅ Protocol Downgrade Prevention: HTTPS → HTTP blocking
✅ TLS/SSL Information: Client certificate extraction
✅ Header Size Limits: 8KB default, configurable
✅ IP Range Filtering: CIDR notation support

🔌 INTEGRATION EXAMPLES

WebSocket with Authentication:

const app = new KeypointJS({ enableWebSocket: true });
const ws = app.enableWebSocket({
  path: '/realtime',
  requireKeypoint: true,
  pingInterval: 30000
});

ws.onConnection((conn) => {
  console.log(`WebSocket connected: ${conn.keypointId}`);
});

gRPC Service Integration:

const app = new KeypointJS({ enableGrpc: true });

// gRPC service definition
const grpcEngine = app.getProtocolEngine().getEngine('grpc');
grpcEngine.addService('auth.AuthService', {
  login: async (ctx) => {
    // Validate via keypoint system
    const token = await authenticate(ctx);
    return { token, expiresIn: 3600 };
  }
});

Mixed Protocol Application:

// Single app handling multiple protocols
app.get('/api/chat', (ctx) => {
  if (ctx.protocol.startsWith('ws')) {
    // WebSocket chat connection
    handleWebSocketChat(ctx);
  } else {
    // HTTP REST API for chat
    return ctx.json({ messages: getChatHistory() });
  }
});
