`create-next-app`: use Turbopack for both dev and build (#82753) Previously, we asked users if they want to use Turbopack for `next dev`. Now, we ask if they want to use Turbopack, and if they do, we use it for both dev and build. It’s also listed as `(recommended)` like App Router. Test Plan: `pnpm build`, `./node_modules/.bin/create-next-app ~/path/to/app`. Choose the Turbopack option. Verify the app uses Turbopack for both dev and build.
