对话撤销：通过 /undo、会话头部按钮或消息下方图标把会话回滚到任意已发送 prompt 之前，文件由插件私有 Shadow Git 快照恢复、会话 fork 成新分支，模型看不到被回滚的回合；附带归档任务设置页与工具卡片按类型着色。

Conversation undo: roll a session back to before any sent prompt via /undo, the session-header button, or the icon under the message, restoring files from a plugin-private shadow-Git snapshot and forking the conversation so the model never sees the reverted turns; includes an Archive Tasks settings page and per-tool colored tool cards.
