fix: 让 5.1 真正可用（显式编码 + 原生 stderr 处理 + .psd1 夹具带 BOM）

上一提交让 5.1 能解析源码，但 Unit 与 Smoke 在 5.1 上仍然是红的。根因是三类彼此
无关的 5.1/7 行为差，全部实测确认：

1) 不写 -Encoding 时，5.1 的 Get-Content / Set-Content 默认是 ANSI，7 是 UTF-8。
   症状是 UTF-8 字节被按 GBK 解出「璇存槑」这类乱码。62 处补上显式 -Encoding UTF8。
   用 AST 而不是正则定位，避免把注释里的散文也改掉。

2) .psd1 夹具用无 BOM 写，而引擎的 .psd1 读取器（Import-PowerShellDataFile）只能靠
   BOM 判断编码、没有参数可传，于是 5.1 按 ANSI 解。40 处夹具改为带 BOM 写 —— 这正是
   .editorconfig 里 [*.psd1] charset = utf-8-bom 本来就要求的，是夹具违反了自己的约定。
   .cmd 批次文件刻意保持无 BOM：cmd.exe 会被 BOM 弄坏。

3) 5.1 在 $ErrorActionPreference = Stop 下会把原生命令写到 stderr 的内容升级成终止性
   NativeCommandError，7 改了这条。takeown/icacls 的 ACL 复位调用、以及 test.ps1 自己
   调子进程的地方，都需要在 Continue 下跑。

验收：test.ps1 9/9 全绿（Encode + Parse + Unit + Smoke + E2E，在 7 与 5.1 上各跑一遍）。

已知未处理（留待后续提交）：tools/lab/** 里还有若干「原生命令 + 2>&1 + Stop」的同类
写法（takeown / icacls / scoop / code / Get-WimInfo）。它们要 Hyper-V 实验机才跑得到，
不在验收门槛内。
