1. Removed icon finding functionality from dci-icon-theme to make it a
pure TUI tool
2. Created new dci-iconfinder tool specifically for icon lookup
operations
3. Changed dci-icon-theme to use QCoreApplication instead of
QGuiApplication
4. Updated version handling to use DTK version macros
5. Removed GUI dependencies from dci-icon-theme
6. Added proper documentation for both tools
This change was necessary to separate concerns and allow dci-icon-theme
to be used in environments without GUI dependencies while maintaining
icon lookup capabilities in a dedicated tool.
refactor: 将图标查找功能移至独立工具
1. 从dci-icon-theme中移除图标查找功能，使其成为纯命令行工具
2. 创建新的dci-iconfinder工具专门处理图标查找操作
3. 将dci-icon-theme改为使用QCoreApplication而非QGuiApplication
4. 更新版本处理以使用DTK版本宏
5. 移除dci-icon-theme对GUI的依赖
6. 为两个工具添加了适当的文档
此变更是为了分离关注点，使dci-icon-theme可以在没有GUI依赖的环境中使用，
同时将图标查找功能保留在专用工具中。
