feat(automaker): enhance feature management and UI components

- Updated `.gitignore` to include agent context files and user-uploaded images for better organization.
- Added "Uncategorized" category to `categories.json` for improved feature classification.
- 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.
- Improved UI components with better styling and responsiveness, including drag-and-drop functionality for project management.

This update significantly enhances the feature management process and user experience within the application.
