fix: исправлена TypeScript ошибка и улучшена обработка ошибок сборки

- Исправлена TypeScript ошибка в login.ts: добавлено поле retryAfter в тип ResponseData
- Улучшена обработка ошибок в manage.sh: добавлена проверка успешности сборки перед проверкой standalone директории
- Предупреждение о missing standalone директории теперь выдает ошибку с подробным описанием
