Launcher (#4)

* 激进的更新

* 试试

* fix.可爱的我一直在修CI（

* fix.启动器一定要能够启动

* feat.尝试弄了AOT的启动器。

* fix.修CI，好像是因为Linux那边有个问题，反正修就对了。

* fix.ci难修，为什么liunx跑不起来呢？

* Update build.yml

* Update LanMountainDesktop.csproj

* changed.调整了启动逻辑，优化了更新页面。

* changed.优化了更新体验

* feat.依旧试增量更新这一块，看看velopack

* fix.我们试验性地修复了启动器无法正常启动的问题，原因可能是这个画面没有启动，就GUI没显示。然后还把编译问题修了一下。

* fix.继续修ci，ci怎么天天炸

* changed.velopack，试试rust

* fix.修ci，修融合桌面，修启动器

* fix.GitHub Action工作流怎么天天出问题

* feat.引入velopack，不好，是rust（至少内存很安全了。
