windterm图标

windterm现在的logo实在是太丑了！现在的软件logo都讲究平滑流线，windterm的logo有很多尖锐的棱角，与现在的主流审美不符。我让AI设计了几个，圆圈里面的我觉得不错。作者要是同意改图标的话我可以帮忙设计几个。

Start by reviewing the attached logo concepts and locating the current application icon assets in the repository. Confirm with the maintainer which concept and platform variants are wanted before proceeding. Done means an agreed replacement icon is prepared and integrated consistently across the application.
