Start by running npm run dev and inspect the TypeScript errors from app/tsconfig.json and tsconfig.json. Compare the missing modules and type declarations with the generated app/package.json and app/yarn.lock; done means the watch build completes without these errors and the side-by-side development workflow runs.
