feat: Enhance model resolution for Cursor models

- Added support for Cursor models in the model resolver, allowing cursor-prefixed models to pass through unchanged.
- Implemented logic to handle bare Cursor model IDs by adding the cursor- prefix.
- Updated logging to provide detailed information on model resolution processes for both Claude and Cursor models.
- Expanded unit tests to cover new Cursor model handling scenarios, ensuring robust validation of model resolution logic.
