Clear and concise description of the problem

The vite plugin of unocss modifies chunk.modules in renderChunk hook for global mode and dist-chunk mode.

This does not work with rolldown-vite because rolldown manages the data on the rust side and chunk.modules is readonly.

If you want to try it out, you can apply this patch by git am -3 ./unocss.patch to this repository and add overrides to point vite to https://pkg.pr.new/rolldown/vite@5cdceeb. pnpm test would fail.

Additional context

Some ideas:

• add an API to Vite so that this ids can be populated
• add an API to rolldown so that chunk.modules can be modified
  • this feels wrong to add that to rolldown, because what we want here is "to tell Vite to include an additional CSS content to a corresponding chunk", rather than "telling rollup/rolldown to add a JS module to that chunk".
• For global mode, it can probably solved by appending an import to a virtual module from every file and delaying the load hook of that virtual module until all the other modules are found.
  • Appending imports is probably not efficient
  • This probably does not work for Chunk mode. Chunk mode requires which module is included in which chunk and that information is only generated after all the transform hooks are called.
