Users are foreced to put "@pika/react" in their dependencies

Users are foreced to put "@pika/react" in their dependencies. Although this is reasonable for app development, it is not suitable for library development.

If user put @pika/react in devDependencies, the optimize step will bundle react into optimized bundle, which leads to duplicate react error in dev. Reproduce: https://github.com/csr632/test-vite/tree/pika-react-dev-dep

vitejs/vite#838 will fix this for most cases. As long as locally developed packages don't have @pika/react installed, that PR will fall back to the app's node_modules.
