macOS 26 uses new design for app icons, with a different corner radius for app icons, making the previous icon unfit for the new version. Hence I created a new icon with the project folder attached (AppIcon.icon).
I also updated the document icon to give it a more modern style. And an icon for temp files (!qB files), and I have edited the info.plist accordingly.
PR #23365.
