Provide option to Preserve directives during build

Describe the feature

I'm building a react library and want to keep "use client" directive during build, but I can't find that option anywhere.

I think this will be only possible in mkdist mode without bundling as it can preserve directives per component file when bundling it isn’t possible.

I tried in mkdist mode but directives are still being ignored with this message :

src/HOC/wrapper.tsx (1:0): Module level directives cause errors when bundled, "use client" in "src/HOC/wrapper.tsx" was ignored.
src/lib/Base.jsx (1:0): Module level directives cause errors when bundled, "use client" in "src/lib/Base.jsx" was ignored.
