修复QQ读不到消息+微信前台判定失败(窗口在前台仍报错)\n\n问题1: QQ(TIM)读不到消息\n 根因: _focus_message_area在窗口未前置前SendKeys({Esc})发给错误窗口\n 然后_read_via_clipboard_once只用{Esc}未能聚焦消息显示区\n TIM中{Esc}只退出搜索到会话列表,非消息区域\n 修复: 删_focus_message_area(整个方法窗口未前置时无意义)\n _read_via_clipboard_once中TIM路径改为:\n {Esc}{Esc}退出搜索→{Down}选中对话→{Enter}打开(加载消息区)\n 此时Ctrl+A选中消息内容而非会话列表\n\n问题2: 微信已前置仍报目标窗口不在前台\n 根因: _cached_hwnd存储UIA NativeWindowHandle(可能是子窗口句柄)\n 而GetForegroundWindow()返回顶层窗口句柄→hwnd不匹配\n 修复: _ensure_hwnd存储时加GetAncestor(hwnd,GA_ROOT)确保存顶层句柄\n _ensure_foreground改用root_hwnd判断\n 加SwitchToThisWindow fallback(权限要求比SetForegroundWindow低)\n \n其他: .gitignore加tim_dump.txt
