背景：Tk.mainloop 的循环条件是 window.is_active(win_id)，而 is_active 对 win_id < 0 直接返回 0 ⇒ 一旦 create_window 失败，app 一次循环都不进、一句日志都不打就 process.exit(0)（现场：Scene3D spawn 后静默退出，「没有窗口」就是这么来的）。改动：window.vp 的 _attach / _connect / create_window 四个失败返回点补 [win] 错误上报（open 失败 / mmap 失败 / desk 未就绪超时 / 请求环压入失败 / CREATED 超时），这些是错误可见性而非临时噪音，长期保留；Scene3D/main.vp 加 _dbg 分步打点（start / tk ok / canvas ok / scene ok / geometry 后的 win_id 与 buf / 渲染线程 / mainloop 返回），用于定位它到底死在哪一步，定位完成后撤除。
