代码审查意见：

1. 在dde-file-manager-pkexec文件中，移除了# Reference:注释，这是一个好的做法，因为注释应该只保留对代码的理解有帮助的信息，而不是指向外部文档的链接。

2. 在LocalFileHandlerPrivate类的注释中，将BUG:https://pms.uniontech.com/bug-view-259909.html替换为BUG:259909，这是一个改进，因为链接可能不再有效，而bug编号应该保持不变。

3. 在emblemhelper.cpp文件中，将feat: https://pms.uniontech.com/story-view-31477.html替换为feat: story 31477，这也是一个改进，因为链接可能不再有效，而story编号应该保持不变。

总体来说，这些更改都是小的改进，旨在提高代码的可读性和维护性。没有发现任何语法或逻辑错误，也没有性能或安全问题。
