feat: Integrate Cursor provider support in AI profiles

- Updated AIProfile type to include support for Cursor provider, adding cursorModel and validation logic.
- Enhanced ProfileForm component to handle provider selection and corresponding model configurations for both Claude and Cursor.
- Implemented display functions for model and thinking configurations in ProfileQuickSelect.
- Added default Cursor profiles to the application state.
- Updated UI components to reflect provider-specific settings and validations.
- Marked completion of the AI Profiles Integration phase in the project plan.
