feat: enhance query handling and testing in ORM

- Introduced `get_session` from `session_manager` for improved session management.
- Added utility function `compile_sql` to streamline SQL compilation.
- Refined imports and streamlined select query calls with alias `sm`.
- Enhanced `QueryWrapper` by adding a docstring for `one()` method.
- Expanded ORM test coverage with `test_basic_query`, refined `test_all_and_count`, and adjusted assertion methods for robustness.
- Added a new attribute `something` to the `ExampleRecord` class for more flexible data representation.
