# 三端一键打包脚本（PowerShell）
# 产物：后端 Linux amd64 + 后端 Windows + 桌面端 Windows NSIS 安装包
# 输出：后端根目录/发版/yyyyMMdd-HHmm/<平台>/
#
# 注意：本脚本必须是 UTF-8 无 BOM + PowerShell 5.1 兼容写法。
# 中文目录名「发版」用码位构造（0x53D1 0x7248），避免 PS5.1 按
# ANSI 读取脚本导致字面量变成乱码目录名。
#
# 用法：在 nl-game-api-gin 目录下执行
#   .\build-all.ps1                # 打全部三端
#   .\build-all.ps1 -SkipDesktop   # 只打后端两端
#   .\build-all.ps1 -SkipLinux -SkipWindows  # 只打桌面端
