Support Vite 8

[nikolawork]

Vite 8 is out: https://vite.dev/blog/announcing-vite8

Even though the migration guide is quite large, it doesn't seem that this project uses Vite except for types in one file so I don't think Vite 8 will break anything.

Thanks for the PR! One thing worth addressing: packages/vite/src/index.ts imports OutputOptions from rollup (line 4), but Vite 8 replaces Rollup with Rolldown — so rollup is no longer available as a transitive dependency.

This won't break at runtime (the import is type-only and erased during compilation), but it will break type-checking and building from source once the repo's own vite devDependency is upgraded to 8.

Suggested fix — inline the type since only dir is used:

-import { OutputOptions } from 'rollup';
 import { Plugin, ResolvedConfig, UserConfig } from 'vite';

-        async writeBundle(outputConfig: OutputOptions) {
+        async writeBundle(outputConfig: { dir?: string }) {

Good catch @AlexVanderbist

I've fixed it in bd6586d

Thanks, looks good! I'll merge this and tag it as a feature release 👍
