Release version 0.15.1

• feat(backup): Export a portable backup of your codeg data and restore from it later. Backups can be passphrase-encrypted, optionally bundle your agent CLI transcripts (Claude, Codex, Gemini, …), and restoring previews the archive and checks version compatibility before doing anything. Your current data is snapshotted first, so a restore can be rolled back if needed.
• feat(file-preview): Added a sandboxed HTML file preview that renders documents safely with scripts disabled, and the preview header now shows the HTML document's title.
• feat(sync): Open conversation tabs and the focused tab now stay in sync across your desktop and browser clients.
• feat(chat): The most recent reply's delegated sub-agents now surface in a top-right overlay, so you can follow delegated work at a glance.
• feat(web): Losing the WebSocket connection now recovers in place through a reconnect dialog, instead of forcing you to log in again.
• feat(chat): Markdown links and file paths in chat now show a type icon in front of them for quicker scanning.
• perf(sidebar): The conversation list is now virtualized for smooth scrolling and rendering even with a large number of conversations; a status change re-renders only the affected card, and sticky folder headers return as a floating overlay.
• fix(chat): Pasting an image from the clipboard now works on Linux and inside the Tauri webview.
• fix(sync): Viewing a shared conversation mid-turn no longer shows a duplicated in-flight prompt or reply.
• chore(registry): Bundled agents updated — Claude Code 0.42.0, OpenCode 1.16.2, Gemini CLI 0.45.2, and OpenClaw 2026.6.1.

发布版本 0.15.1

• 功能(备份)：现在可以导出一份可移植的 codeg 数据备份，并在之后随时恢复。备份支持口令加密，可选择一并打包各代理 CLI 的会话记录（Claude、Codex、Gemini 等）；恢复前会预览备份内容并检查版本兼容性，且会先对当前数据做快照，必要时可回滚本次恢复。
• 功能(文件预览)：新增沙箱化的 HTML 文件预览，默认禁用脚本以安全渲染文档，预览标题栏还会显示 HTML 文档的标题。
• 功能(同步)：已打开的会话标签页与当前聚焦的标签页现在会在桌面端与浏览器端之间保持同步。
• 功能(聊天)：最近一条回复所委派的子代理现在会汇总到右上角浮层，让你一眼掌握委派任务的进展。
• 功能(网页)：WebSocket 连接断开时，现在通过重连对话框就地恢复，不再强制重新登录。
• 功能(聊天)：聊天中的 Markdown 链接和文件路径前会显示类型图标，浏览时更易辨识。
• 性能(侧边栏)：会话列表改为虚拟化渲染，会话数量很多时滚动与渲染依然流畅；状态变更只重绘对应的会话卡片，粘性文件夹标题以浮动覆盖层的形式回归。
• 修复(聊天)：在 Linux 及 Tauri webview 中，从剪贴板粘贴图片现已可用。
• 修复(同步)：在会话进行中途查看共享会话时，不再出现重复的进行中提问或回复。
