- Populated `feature_list.json` with new features, including detailed descriptions and image attachments for better context.
- Changed application icon to `icon_gold.png` for a refreshed look.
- Enhanced `AutoModeService` to support max concurrency and periodic checks, improving feature execution management.
- Updated image handling in `DescriptionImageDropZone` to save images in the project directory.
