.SYNOPSIS
  一键打包脚本。

.DESCRIPTION
  默认产出「绿色免安装版」到 dist\qiweimanager\（不需要 NSIS，解压即用）：
    1. 定位 Go / Wails 工具链并注入 PATH。
    2. 32 位编译 helper.exe；编译 silk 音频解码器。
    3. wails build 生成主程序 qiweimanager.exe（前端一并编译）。
    4. 汇总主程序 + helper + DLL + 工具 + 默认配置到 dist 目录。

  指定 -Installer 时，额外调用现有的 scripts\package-windows.ps1 走 NSIS 生成安装包
  （需本机已安装 NSIS）。

.PARAMETER Installer
  额外生成 NSIS 安装包（委托 package-windows.ps1，需要 makensis）。

.PARAMETER SkipTests
  跳过 go test。

.PARAMETER GoPath / WailsPath
  手动指定工具路径（自动探测失败时使用）。

.EXAMPLE
  powershell -ExecutionPolicy Bypass -File scripts\build.ps1
  powershell -ExecutionPolicy Bypass -File scripts\build.ps1 -Installer
