What's new in 2.2.2

ZZZ 2.2.2 包含 5 项改进，全部附带新增边界测试（CI 于 windows-latest 构建三架构并通过全部测试）：

  • 快捷键修复与补齐：修复 Alt+Left / Alt+Right / Alt+D 在启动页、地址栏等 WPF 原生界面完全失效的问题（WPF 将 Alt 组合键报告为 Key.System）；新增 F5 刷新、Ctrl+Tab / Ctrl+Shift+Tab（及 Ctrl+PageDown / Ctrl+PageUp）循环切换标签、Ctrl+1–Ctrl+8 直达对应标签、Ctrl+9 跳到最后一个、Ctrl+D 收藏/取消收藏、Ctrl+H 资料库、Ctrl+J 下载列表；网页获得焦点时同样生效，并支持鼠标中键关闭标签页。
  • Ctrl+Shift+T 重新打开最近关闭的标签页：会话内记录最近 25 个已关闭的普通标签，按后进先出恢复到原工作区；隐私标签与内置启动页从不记录，列表仅保存在内存中、从不落盘。
  • 历史记录写入合并：访问页面不再每次导航都对最多 3000 条记录重新加密并整写 history.dat，改为约 3 秒后台合并写入；删除单条、清空历史与退出流程仍即时落盘，显著降低磁盘 I/O 与便携存储磨损。
  • 下载启动稳健化：下载目录无效或不可写时自动回退（配置目录 → 用户"下载"文件夹 → TEMP），不再在 WebView2 下载事件内抛异常导致浏览器崩溃；外部下载器参数模板缺少 {url} 时自动附加下载地址，内嵌引号以 %22 转义。
  • 版本号单一来源（AppVersion）：用户脚本 GM_info 与广告规则更新、脚本导入、网站图标抓取的 User-Agent 均引用同一常量，边界测试锁定程序集版本与其一致；本 Release 的三架构 EXE 由新增的 tag 触发工作流自动构建并附带 SHA-256 清单。

完整变更见 CHANGELOG.md。官网与 R2 下载服务同步更新到 2.2.2。
