The eslint-plugin-prefer-arrow-functions plugin has a hardcoded
exemption in guard.js:hasNameAndIsExportedAsDefaultExport that silently
passes named default-exported function declarations regardless of any
configuration option. Add a companion no-restricted-syntax selector
(ExportDefaultDeclaration > FunctionDeclaration) inside the
prefer-arrow config block to close the gap. Ignore *.d.ts since ambient
signatures have no body to convert.
Convert offenders to: const Name = () => {}; export default Name;
