Implement HTTP/2 and WebSocket support; remove legacy JavaScript and CSS files

- Added HTTP/2 support in src/http2.c and src/http2.h, including session management, frame handling, and response sending.
- Introduced WebSocket functionality in src/websocket.c and src/websocket.h, covering handshake, frame parsing, and message sending.
- Created a WebSocket test page (www/websocket-test.html) for client-side interaction.
- Removed outdated JavaScript (www/script.js) and CSS (www/style.css) files.

+### WebSocket Usage
+
+Carbon includes full WebSocket support for real-time bidirectional communication.
+
+**JavaScript Client Example:**
+```javascript
+// Connect to WebSocket server
+const ws = new WebSocket('ws://localhost:8080');
+
+// Connection opened
+ws.addEventListener('open', (event) => {
+    console.log('Connected to server');
+    ws.send('Hello Server!');
+});
+
+// Listen for messages
+ws.addEventListener('message', (event) => {
+    console.log('Message from server:', event.data);
+});
+
+// Handle errors
+ws.addEventListener('error', (error) => {
+    console.error('WebSocket error:', error);
+});
+
+// Connection closed
+ws.addEventListener('close', (event) => {
+    console.log('Disconnected from server');
+});
+```
+
+**Secure WebSocket (wss://):**
+```javascript
+const wss = new WebSocket('wss://your-domain.com');
+// Same API as above
+```
+
+**Testing with wscat:**
+```bash
+# Install wscat
+npm install -g wscat
+
+# Connect to WebSocket server
+wscat -c ws://localhost:8080
+
+# Connect to secure WebSocket
+wscat -c wss://localhost:443 --no-check
+
+# Type messages and press Enter to send
+# The server will echo them back
+```
+
+**Python Client Example:**
+```python
+import websocket
+
+def on_message(ws, message):
+    print(f"Received: {message}")
+
+def on_open(ws):
+    print("Connected")
+    ws.send("Hello from Python!")
+
+ws = websocket.WebSocketApp("ws://localhost:8080",
+                           on_message=on_message,
+                           on_open=on_open)
+ws.run_forever()
+```
+
+### HTTP/2 Support
+
+Carbon includes full HTTP/2 support with automatic protocol negotiation via ALPN.
+
+**Features:**
+- ✅ HTTP/2 server push (stream multiplexing)
+- ✅ HPACK header compression
+- ✅ Binary framing protocol
+- ✅ Automatic fallback to HTTP/1.1
+- ✅ ALPN protocol negotiation
+- ✅ Server-side stream management
+
+**Configuration:**
+
+Enable HTTP/2 in `server.conf`:
+```ini
+use_https = true
+enable_http2 = true
+https_port = 443
+```
+
+**Testing HTTP/2:**
+
+```bash
+# Test with curl (verbose)
+curl -v --http2 -k https://localhost:443/
+
+# Check ALPN negotiation
+openssl s_client -connect localhost:443 -alpn h2 < /dev/null 2>&1 | grep "ALPN protocol"
+
+# Test with h2load (load testing)
+h2load -n 1000 -c 10 https://localhost:443/
+
+# Use the diagnostic script
+./check-http2.sh
+```
+
+**Browser Support:**
+
+All modern browsers support HTTP/2:
+- ✅ Chrome/Chromium 40+
+- ✅ Firefox 36+
+- ✅ Safari 9+
+- ✅ Edge (all versions)
+- ✅ Opera 27+
+
+Browsers automatically negotiate HTTP/2 when connecting to HTTPS sites that support it.
+
+**Performance Benefits:**
+
+HTTP/2 provides significant performance improvements:
+- **Multiplexing**: Multiple requests over a single connection
+- **Header Compression**: Reduced overhead with HPACK
+- **Server Push**: Proactive resource delivery
+- **Binary Protocol**: More efficient parsing
+- **Stream Prioritization**: Better resource loading
+
+See [HTTP2_TESTING.md](HTTP2_TESTING.md) for detailed testing instructions.

+            <p>To enable HTTPS support, you'll need SSL certificates. You can use self-signed certificates for testing or obtain certificates from Let's Encrypt for production.</p>
+            
+            <h3>Generate Self-Signed Certificates (Testing Only)</h3>
+            <pre><code># Create certificates directory
+mkdir -p certs
+
+# Generate self-signed certificate
+openssl req -x509 -newkey rsa:4096 -nodes \
+    -keyout certs/key.pem \
+    -out certs/cert.pem \
+    -days 365 \
+    -subj "/C=US/ST=State/L=City/O=Organization/CN=localhost"</code></pre>
+            
+            <h3>Enable HTTPS in Configuration</h3>
+            <pre><code># Edit server.conf
+use_https = true</code></pre>
+            
+            <div class="warning-box">
+                <strong>Warning:</strong> Self-signed certificates will show security warnings in browsers. For production, use certificates from a trusted Certificate Authority like Let's Encrypt.

+            <p>Carbon includes full WebSocket support (RFC 6455 compliant) for building real-time applications.</p>
+            
+            <h3>Test WebSocket Connection</h3>
+            <p>Use the built-in test client:</p>
+            <pre><code># Browser
+http://localhost:8080/websocket-test.html
+
+# Command line (requires wscat: npm install -g wscat)
+wscat -c ws://localhost:8080
+
+# Secure WebSocket (if HTTPS enabled)
+wscat -c wss://localhost:443</code></pre>
+            
+            <h3>JavaScript Example</h3>
+            <pre><code>// Connect to WebSocket server
+const ws = new WebSocket('ws://localhost:8080');
+
+// Connection opened
+ws.addEventListener('open', (event) => {
+    console.log('Connected!');
+    ws.send('Hello Server!');
