fix(eui-neo): install() 里的布局归一不能用 shell —— Windows 上没有

`workspace (windows default 0/1)` 红。install() 是**每个平台都跑**的,而里面
那段归一 wrap 层的逻辑用了 `sh -c`;Windows runner 上没有这个东西。Linux 与
macOS 都过了,正好说明问题只在这一处。

改成纯 xmake Lua:按名字**问**归档的形状,而不是去**发现**它 ——
这个沙箱里既没有 `os.files` 也没有 `path.basename`,列目录本来就做不到。
四个候选名覆盖 GitHub 的 `EUI-NEO-<v>` 与镜像可能的小写/带 v 拼法;真扁平的
包走 `os.cp("*", layer)`。

`stage_glib` 里的 `cp -a` 保留,并写明理由:那一支被 `os.host() ~= "linux"`
挡住,而且 glib 的 `libgio-2.0.so -> .so.0 -> .so.0.8000.0` 是符号链接,
解引用会变成三份完整拷贝并丢掉链接器解析的那个名字。

本机复验:三项 lint 通过,消费者仍然 `eui_tray_init -> 1`。
