📚 Description

Currently, the construction export { xyz as default } is not recognized as a valid default export by the default-export vite plugin. Thus, a second default export is added, which leads to an error.
An example is
https://github.com/posva/pinia/blob/a76e34387419e86154a63985ad038eefeb2bc9fd/packages/nuxt/src/templates/plugin.ts#L50
which is transpiled as export { PiniaNuxtPlugin as default }; in the distributed build. (cc @posva)

This is fixed by adding a regex-based check.
