                                // 默认（压缩）非 const 构建的 launcher。ps12exe 把真正的托管程序集压缩后作为 "main" 资源塞进这个 launcher，launcher 启动时在内存里解压、Assembly.Load 后调用负载的入口点，负载不落盘。Windows PowerShell（CodeDom）下负载用 gzip；PowerShell Core 下用 Brotli（压缩率更高，但 .NET Framework 不提供 BrotliStream）。资源/版本属性在打包时由本 launcher 携带（公共源 src/programFrames/AssemblyInfo.cs，见 CodeDomCompiler.ps1 / Core 的 csproj）。
