- Downloaded official SVG icons from Slint repository
- Added square logos for file type icons (light and dark variants)
- Added full logos for larger display areas
- Implemented automatic theme switching (slintFile.svg / slintFile_dark.svg)
- Replaced old PNG icon with scalable SVG icons
- Updated SlintIcons to use IconLoader for proper SVG support
Icons now properly display in IntelliJ and adapt to light/dark themes.
