'use client'

Hi, I'm the maintainer of [react-lenis](https://github.com/studio-freight/react-lenis) package and some people complain about using the library in next.js app context usage.
In fact it requires 'use client' directive on top of the file but I noticed that it's ignored by microbundle "Module level directives cause errors when bundled, 'use client' was ignored."
Do you have a solution for that ?

先在 Next.js 應用程式中重現回報的套件使用方式，並檢查 Microbundle 在打包期間如何處理模組層級的 'use client' 指示詞。issue 中沒有指定檔案或測試；完成條件是保留該指示詞，或以其他方式支援該指示詞，且不再出現回報的警告。
