 * Creates a generated ESM entry module that re-exports runtime modules through
 * one stable file.
 *
 * @remarks
 * Integrations use this helper when they need a browser runtime asset composed
 * from multiple bare specifiers but do not want to own temporary file assembly
 * logic themselves. The generated file lives under the app work directory so
 * repeated runs can reuse the same location without placing sources inside
 * `node_modules`, which can cause bundlers to externalize bare imports.
