refactor: update repository methods to improve query handling and remove deprecated tests
- Refactored `findRows` method to `find` in the Repository class for consistency. - Updated return types for `insert`, `update`, and `delete` methods to return QueryResult instead of single rows. - Enhanced SQL query building in SelectQueryBuilder to handle optional limit and offset correctly. - Removed outdated test files for `findRow`, `findRows`, `insertMany`, and `insertOne` to streamline the test suite. - Improved type handling in test setup and assertions for better type safety.
