+     * The fully compiled execution pipeline for this route.

+     * This function is generated at route registration time and encapsulates the
+     * entire middleware chain as well as the final handler. It is called by the
+     * HttpKernel during request dispatch when a route has been matched.
+     *
+     * Internally, `runRoute` ensures that each middleware is invoked in the correct order
+     * and receives a `next()` callback to pass control downstream. The final handler is
+     * invoked once all middleware has completed or short-circuited the pipeline.
+     *
+     * It is guaranteed that:
+     * - The function is statically compiled and does not perform dynamic dispatching.
+     * - Each middleware can only call `next()` once; repeated invocations will throw.
+     * - The return value is either a `Response` or a Promise resolving to one.
+     *
+     * @param ctx - The context object carrying route, request, response and other scoped data.
+     * @returns A `Response` object or a Promise resolving to a `Response`.
+     *
+     * @throws {Error} If a middleware calls `next()` more than once.
