feat: enhance adaptive thinking model support and update UI components

- Added `isAdaptiveThinkingModel` utility to improve model identification logic in the AddFeatureDialog.
- Updated the ThinkingLevelSelector to conditionally display information based on available thinking levels.
- Enhanced model name formatting in agent-context-parser to include 'GPT-5.3 Codex' for better clarity.

These changes improve the user experience by refining model handling and UI feedback related to adaptive thinking capabilities.
