     * - `getaddrinfo` - Uses the posix standard `getaddrinfo` function. Will cause performance issues under concurrent loads.
     *
     * To customize the DNS resolver, pass a `backend` option to `dns.lookup`:
     * ```js
     * import { dns } from 'bun';
     * const [{ address }] = await dns.lookup('example.com', {backend: 'getaddrinfo'});

         *
         * On macOS, `system` uses the builtin macOS [non-blocking DNS

         * API](https://opensource.apple.com/source/Libinfo/Libinfo-222.1/lookup.subproj/netdb_async.h.auto.html).
         *
         * On Linux, `system` is the same as `getaddrinfo`.

         * potentially pause until the DNS lookups are done.

  /**
   * Bun.serve provides a high-performance HTTP server with built-in routing support.
   * It enables both function-based and object-based route handlers with type-safe
   * parameters and method-specific handling.
   *
   * @param options - Server configuration options
   *
   * @category HTTP & Networking
   *
   * @example Basic Usage
   * ```ts
   * Bun.serve({
   *   port: 3000,
   *   fetch(req) {
   *     return new Response("Hello World");
   *   }
   * });
   * ```
   *
   * @example Route-based Handlers
   * ```ts
   * Bun.serve({
   *   routes: {
   *     // Static responses
   *     "/": new Response("Home page"),
   *
   *     // Function handlers with type-safe parameters
   *     "/users/:id": (req) => {
   *       // req.params.id is typed as string
   *       return new Response(`User ${req.params.id}`);
   *     },
   *
   *     // Method-specific handlers
   *     "/api/posts": {
   *       GET: () => new Response("Get posts"),
   *       POST: async (req) => {
   *         const body = await req.json();
   *         return new Response("Created post");
   *       },
   *       DELETE: (req) => new Response("Deleted post")
   *     },
   *
   *     // Wildcard routes
   *     "/static/*": (req) => {
   *       // Handle any path under /static/
   *       return new Response("Static file");
   *     },
   *
   *     // Disable route (fall through to fetch handler)
   *     "/api/legacy": false
   *   },
   *
   *   // Fallback handler for unmatched routes
   *   fetch(req) {
   *     return new Response("Not Found", { status: 404 });
   *   }
   * });
   * ```
   *
   * @example Path Parameters
   * ```ts
   * Bun.serve({
   *   routes: {
   *     // Single parameter
   *     "/users/:id": (req: BunRequest<"/users/:id">) => {
   *       return new Response(`User ID: ${req.params.id}`);
   *     },
   *
   *     // Multiple parameters
   *     "/posts/:postId/comments/:commentId": (
   *       req: BunRequest<"/posts/:postId/comments/:commentId">
   *     ) => {
   *       return new Response(JSON.stringify(req.params));
   *       // Output: {"postId": "123", "commentId": "456"}
   *     }
   *   }
   * });
   * ```
   *
   * @example Route Precedence
   * ```ts
   * // Routes are matched in the following order:
   * // 1. Exact static routes ("/about")
   * // 2. Parameter routes ("/users/:id")
   * // 3. Wildcard routes ("/api/*")
   *
   * Bun.serve({
   *   routes: {
   *     "/api/users": () => new Response("Users list"),
   *     "/api/users/:id": (req) => new Response(`User ${req.params.id}`),
   *     "/api/*": () => new Response("API catchall"),
   *     "/*": () => new Response("Root catchall")
   *   }
   * });
   * ```
   *
   * @example Error Handling
   * ```ts
   * Bun.serve({
   *   routes: {
   *     "/error": () => {
   *       throw new Error("Something went wrong");
   *     }
   *   },
   *   error(error) {
   *     // Custom error handler
   *     console.error(error);
   *     return new Response(`Error: ${error.message}`, {
   *       status: 500
   *     });
   *   }
   * });
   * ```
   *
   * @example Server Lifecycle
   * ```ts
   * const server = Bun.serve({
   *   // Server config...
   * });
   *
   * // Update routes at runtime
   * server.reload({
   *   routes: {
   *     "/": () => new Response("Updated route")
   *   }
   * });
   *
   * // Stop the server
   * server.stop();
   * ```
   *
   * @example Development Mode
   * ```ts
   * Bun.serve({
   *   development: true, // Enable hot reloading
   *   routes: {
   *     // Routes will auto-reload on changes
   *   }
   * });
   * ```
   *
   * @example Type-Safe Request Handling
   * ```ts
   * type Post = {
   *   id: string;
   *   title: string;
   * };
   *
   * Bun.serve({
   *   routes: {
   *     "/api/posts/:id": async (
