rem  观澜 start.bat
rem  2026-09-16 用户令: 启动观澜系统时"弹出的命令窗口"改为不弹出方式。
rem  2026-09-16 用户令二: **把 VBScript 替换掉** —— 原先无窗口启动靠 start_hidden.vbs
rem                      (WScript.Shell.Run 窗口样式 0)。现改为直接用 pythonw.exe(无控制台子系统的
rem                      解释器) 跑启动器: 不经过 Windows 脚本宿主, WSH 被组策略禁用/未安装的
rem                      服务器上照样能用。
rem
rem  默认 (双击本文件)      : pythonw.exe 无窗口起服务 + 等就绪 + 自动开浏览器。
rem                           ★ .bat 本身是控制台程序, 双击时 Windows 必定先开一个窗口; 本脚本会让它
rem                             在零点几秒内自己关掉 (脚本内无法消除这个闪窗)。要**完全不闪窗**:
rem                             用安装时生成的 `启动观澜.lnk`(目标 = .venv\Scripts\pythonw.exe),
rem                             它不经过 cmd.exe, 一个窗口都不会出现。
rem  start.bat console      : 前台模式 (旧行为) —— 在当前窗口里跑 serve 并实时打印日志,
rem                           只在排障时用; 关掉这个窗口等于停掉 serve。
rem  start.bat help         : 说明。
rem
rem  为什么分开: 各组件服务本来就是 DETACHED_PROCESS 起的 (不弹窗), 唯一会弹的就是
rem  "在控制台里前台跑 guanlan.py serve" 这件事本身。排障又确实需要看见实时输出,
rem  所以保留一个显式的 console 档, 而不是把日志彻底藏掉。
