ClassHelper/scripts/nsis/server-installer.nsi

; 班级小助手服务端 + Web 管理端 Windows 安装程序
; 由 scripts/dist-server.mjs 生成（占位符在打包时替换）
;
; 设计要点：
; - 当前用户级安装（$LOCALAPPDATA\Programs），无需管理员权限即可完成安装
; - 内置 Node 运行时，目标机无需安装 Node.js
; - 快捷方式：启动/停止/重启服务、打开管理端、卸载
; - 默认加入当前用户开机自启（注册表 HKCU\...\Run），随时可用
; - 卸载时保留 data 目录（数据库）以避免误删数据
