           * Pages Function handler for all routes.
           *
           * This catch-all route handler processes all incoming requests to the Xget
           * acceleration engine. It delegates request processing to the main handleRequest
           * function from the Workers code, maintaining full compatibility with the
           * existing implementation.
           *
           * The [[path]] syntax in the filename creates a catch-all route that matches
           * any path, allowing this single function to handle all requests to the Pages
           * application.
           *
           * @param {Object} context - Pages Function context
           * @param {Request} context.request - The incoming HTTP request
           * @param {Object} context.env - Environment variables and bindings (KV, secrets, etc.)
           * @param {Object} context.params - Route parameters (path segments from [[path]])
           * @param {Function} context.waitUntil - Extend function execution for background tasks
           * @param {Function} context.next - Call next middleware in chain (not used here)
           * @param {Object} context.data - Shared data between functions
           * @returns {Promise<Response>} The HTTP response to return to the client
           *
           * @example
           * // This is called automatically by Pages
           * // Runtime invokes: onRequest(context)
           * // Returns: Response with package data
           *
           * @example
           * // Environment variables usage
           * // wrangler.toml: [vars] TIMEOUT_SECONDS = "60"
           * // context.env contains: { TIMEOUT_SECONDS: "60" }
           * // handleRequest uses createConfig(env) to override defaults
