feat: Enhance Cursor model selection and profile handling

- Updated AddFeatureDialog to support both Cursor and Claude profiles, allowing for dynamic model and thinking level selection based on the chosen profile.
- Modified ModelSelector to filter available Cursor models based on global settings and display a warning if the Cursor CLI is not available.
- Enhanced ProfileQuickSelect to handle both profile types and improve selection logic for Cursor profiles.
- Refactored CursorSettingsTab to manage global settings for enabled Cursor models and default model selection, streamlining the configuration process.
