fix: disable sourceMap output to prevent source-map-loader errors in consumers

When installed via file: reference, CRA's source-map-loader follows relative
paths in .js.map files that escape the project root through the symlink,
causing ENOENT. Disabling source maps removes the .map files entirely.
