从组词里起手的那一次 Backspace 按住，一旦 composition 被删空， 同一次按住的后续 auto-repeat 一并吞掉；松开后重新按下才恢复退格。 - 新增 KeyRepeatGuard 纯谓词（repeat 位判定，不依赖 keyup、不用计时器）+ x64/x86 单测 - OnTestKeyDown / _DispatchKeyDown / _ClassifyDeferredKeyDown 三处同判据： 吞键不发 IPC、不请求编辑会话，命中的排队键完成 replay token - 延迟投影把 inputLength 打到 0 时置位，慢 Server 下重放不会漏到宿主 - 焦点/上下文清理路径复位（OnSetFocus、_ClearDeferredKeyDowns、 ThreadFocusSink::OnKillThreadFocus），不在 Chromium 文档切换路径误复位 Refs #347
