fix(shadcn): missing default condition in exports["./tailwind.css"] breaks Turbopack #10931

Describe the bug

apps/v4/app/globals.css imports shadcn/tailwind.css, but the exports field in packages/shadcn/package.json only has a "style" condition for that entry — no "default" fallback. Turbopack's resolver doesn't recognize the bare "style" condition without one, so the import fails with a CssSyntaxError.

Every other entry in the exports map has a "default" alongside "types", so this looks like it was just missed for the CSS entry.

Affected component/components

shadcn CLI (packages/shadcn)

How to reproduce

1. Clone the repo fresh
2. Run pnpm install and pnpm --filter=shadcn build
3. Start the apps/v4 dev server
4. Browser shows: CssSyntaxError: tailwindcss: Can't resolve 'shadcn/tailwind.css'
