ModelCollection for List-Based Model Management

Future Considerations

1. Consider adding more specialized collection types (e.g., ordered, sorted)
2. Evaluate performance with large collections (1000+ items)
3. Consider adding collection-level operations (filter, map, reduce)
4. Potential for async/lazy loading of items for very large datasets
5. Integration with numpy arrays or pandas DataFrames for numerical operations
