description	Add a shadcn/ui primitive correctly into the frontend.

Use when the user asks to add a shadcn primitive.

1. cd frontend && npx shadcn@latest add <component> (e.g. dialog, dropdown-menu, input, select).
2. The command writes to src/components/ui/. Don't hand-edit those files; they are regenerated when shadcn ships updates.
3. Import via @/components/ui/<component> and use the cn() helper from @/lib/utils for any conditional class names.
4. If the primitive needs a new Radix peer, the shadcn CLI adds it to package.json automatically; commit package.json and yarn.lock together.
5. Re-run yarn lint && yarn typecheck to make sure the addition didn't break anything.
