Add pinia; switch vite to rolldown-vite in lock

Add Pinia (^3.0.4) to packages/ui/package.json and regenerate pnpm-lock.yaml. The lockfile now includes pinia metadata, Vue devtools entries, several new/updated packages, and replaces references to vite with rolldown-vite across snapshots and package resolutions (generated dependency updates).
