merge: update from main branch — Vite 8 + @vitejs/plugin-react 6.0.1

Merges latest main which bumps vite from 7.3.1 to 8.0.0 and
@vitejs/plugin-react from 5.1.4 to 6.0.1. The previous v5.2.0
downgrade is no longer needed since Vite 8 is now the base.

Resolves lockfile conflicts and confirms build + tests pass.
