feat: upgrade vite to v8.0.0-beta.8 (Rolldown-powered) (#8127)

Browse Source

## Summary

Upgrades Vite from v7.3.0 to v8.0.0-beta.8, which uses Rolldown
(Rust-based bundler) instead of Rollup.

## Changes

- Updated `vite` to `^8.0.0-beta.8` in pnpm-workspace.yaml catalog
- Added pnpm overrides to ensure all dependencies (including vitest) use
Vite 8

## Notes

- Vite 8 is still in **beta** - no stable release yet
- Uses [Rolldown](https://rolldown.rs/) instead of Rollup for production
builds
- Build, typecheck, and lint all pass
- Per the [Vite 8 migration
guide](https://vite.dev/blog/announcing-vite8-beta), pnpm overrides are
required for tools like Vitest that bundle their own Vite types

## Testing

- [x] `pnpm typecheck` passes
- [x] `pnpm build` succeeds (~13s build time)
- [x] `pnpm lint` passes
