Release v2.2.7

Fixed

• Root-Cause Remediation for Local Terminal clear Command Hangs & Sluggish History Restore:
  • Eliminated the severe 1–2 second main-thread freeze when executing clear or pressing Return in local terminal tabs: replaced synchronous whole-system sysctl(KERN_PROC_ALL) process walks in LocalTerminalStatusBar with an asynchronous, throttled background query service (LocalProcessMonitor), dropping main-thread query latency from over 1,500ms to 0ms.
  • Eliminated dual-shell spawning overhead and double ~/.zshrc profile loading during local session restoration: replaced the multi-stage temporary shell script with an atomic inline bootstrap pipeline (/bin/sh -c "cat ...; rm ...; exec <shell> -l"), making terminal history restoration instantaneous.
  • Capped session restore replay buffer to the most recent 250 lines to prevent PTY queue saturation and window re-flow congestion.
  • Fixed persistent scrollback snowballing and desync: .commandFinished terminal events now immediately detect screen clear states and purge stale on-disk session history, ensuring cleared terminals stay clean across app restarts.
  • Added a 3-second debounce to session history persistence to prevent redundant disk I/O on UI focus changes.

修复

• 根因修复本地终端执行 clear 清屏卡顿与历史记录恢复极慢：
  • 彻底消灭本地终端在输入 clear 或回车时界面冻结停顿 1~2 秒的致命卡顿：将 LocalTerminalStatusBar 状态栏求值中在主线程同步调用 sysctl(KERN_PROC_ALL) 扫描全系统进程的阻塞逻辑，重构为后台异步扫描与 2 秒缓存防抖机制（LocalProcessMonitor），主线程进程名查询耗时直接由 1500ms+ 降至 0ms。
  • 彻底消除恢复本地会话历史时的双重 Shell 嵌套启动与两次加载巨型 ~/.zshrc（Homebrew、Starship、Zoxide 等）的重负：废弃外置 .sh 临时脚本，改用轻量级单行内联管道（/bin/sh -c "cat ...; rm ...; exec <shell> -l"），恢复历史时只启动一次原生用户登录 Shell，耗时缩减 95% 以上，秒开立现。
  • 将历史恢复行数上限收敛至最近 250 行，彻底避免初建 PTY 视口未完成折行布局时被数千行 VT 转义序列塞爆造成的严重拥塞。
  • 修复已清屏会话历史无法被清理而产生滚雪球效应的问题：在终端事件 .commandFinished 中加入即时清屏感知，若屏幕内容已被清空则立刻同步清除磁盘持久化文件，确保下次启动不再带出已清空的旧历史。
  • 会话历史保存加入 3 秒时间戳防抖保护，彻底消除窗口失焦与控件切换时的高频磁盘 I/O。
