## Description

Create transparent attribute access methods that make auxiliary table columns appear as native model attributes

## Acceptance Criteria

- [x] Getter methods return auxiliary column values
- [x] Setter methods create/update auxiliary records automatically
- [x] Presence check methods work correctly
- [x] Methods are defined lazily using method_missing
- [x] All tests pass
## Implementation Notes

Implemented lazy loading attribute accessors using method_missing override. When an auxiliary attribute is accessed (e.g., car.fuel_type), the system checks if it's a valid auxiliary column and dynamically defines the getter, setter, and presence check methods. This follows ActiveRecord's lazy loading pattern and provides transparent access to auxiliary table columns.
