叫我小杨同学 d6c97a49ed fix(desktop): PowerShell 立即 kill Electron 消除 #64 crash dialog 根因
- ASAR_SWAP_PS1 不再等 WaitPid 优雅退出,改为立即 Stop-HarnessInstall;
  Electron main 和 host 一起被 kill,UI 来不及收 host 退出事件,
  main.js:3725 的"host stopped"对话框根本没机会显示。
  PowerShell 是 detached+stdio:ignore 独立进程,杀 Electron 不影响自己。
- scheduleAsarSwapRestart 接 ctx fallback,启动期自愈路径也能解析
  desktopRuntime 走 requestRestart 做双保险。
- gracefulExit timeout 从 4500/3000 缩到 2000/1500ms:PS 杀得快,
  不需要那么长的 handoff 窗口兜底。
- core.restartSealedDesktopIfNeeded 透传 input.ctx 给桌面层两条路径。
- index.js:scheduleApplyRestart / handlePurgeCommand 全链路加 ctx 参数,
  commands.register handler 把 effect 作用域 ctx 交到最深处的
  restartSealedDesktopIfNeeded 和 scheduleRestart。
- identity.js:isHardcodedExecRule 长度闸 800→1500,用户 rules 文件偶尔
  引用写死 preamble + 本体 >800 字节时不再被误剥。
