Implementation
@override
Future<void> addGoRouter(String projectName) async {
// This method is called when Go Router is added to an existing project
// We need to get the current state management type from the project
// For now, we'll assume it's none and let the main createProject handle the integration
// Create Go Router templates
await _fileSystemDataSource.createGoRouterTemplates(projectName);
