The login page references 'images/logo.svg' via vite()->asset(), which requires
the file to be present in the build manifest. Adding it to the input array
ensures it is processed and listed in manifest.json.
This ensures that Vite treats the configuration files as ESM, allowing them to
natively import 'laravel-vite-plugin' (which is ESM-only). This resolves the
build error where esbuild was converting imports to require() calls in CJS packages,
causing the build to fail.
