 * Model representing an ingress rule for a Cloudflare Tunnel.

 * <p>Ingress rules define how incoming requests should be routed through
 * the tunnel to your internal services. Each rule specifies:</p>
 * <ul>
 *   <li>{@link #hostname} - The domain/subdomain to match</li>
 *   <li>{@link #service} - The internal service URL</li>
 *   <li>{@link #originRequest} - Optional settings for origin requests</li>
 *   <li>{@link #path} - Optional path prefix to match</li>
 * </ul>

 * <p><b>Example JSON:</b></p>
 * <pre>
 * {
 *   "hostname": "api.example.com",
 *   "service": "http://localhost:8080",
