feat(artifact): 产物系统优化 — 共享渲染 + 数据源扩展 + 持久化

- MarkdownRenderer: 从 StreamingText 提取共享 react-markdown + remark-gfm 组件
- ArtifactPanel: 替换手写 MarkdownPreview 为完整 GFM 渲染，添加文件选择器下拉菜单
- 数据源: file_write/str_replace 双工具 + sendMessage/initStreamListener 双路径
- 持久化: artifactStore 添加 zustand persist + IndexedDB (复用 idb-storage)

+# 产物系统参考文档
+
+> 调研 DeerFlow 和 Hermes Agent 的产物/输出面板实现，为 ZCLAW 产物系统重构提供参考。
+> 分析日期：2026-04-24
+
+---
+
+## 一、DeerFlow 产物系统
+
+DeerFlow 有完整的全栈产物管道，是主要参考对象。
+
+### 1.1 端到端数据流
+
+```
+Agent tool call (write_file / str_replace / present_files)
+    ↓
+Backend: ThreadState.artifacts (LangGraph annotated list, merge_artifacts reducer 去重)
+    ↓ 文件写入: {base_dir}/threads/{thread_id}/user-data/outputs/
+    ↓ 虚拟路径: /mnt/user-data/outputs/filename.ext
+    ↓
+Backend API: GET /api/threads/{thread_id}/artifacts/{virtual_path}
+    ↓ MIME 检测 / .skill ZIP 解压 / download vs inline
+    ↓
+Frontend: thread.values.artifacts (string[]) → ArtifactsProvider context
+    ↓
+ChatBox (ResizablePanelGroup) → chat(60%) | artifact panel(40%)
+    ↓
+ArtifactFileDetail → CodeMirror(代码) / Streamdown(Markdown) / iframe(HTML)
+```
+
+### 1.2 关键文件
+
+#### 前端核心
+
+| 文件 | 职责 |
+|------|------|
+| `frontend/src/core/artifacts/utils.ts` | URL 构建、产物列表提取、路径解析 |
+| `frontend/src/core/artifacts/loader.ts` | 从后端 API 获取产物文本；从 tool call args 直接提取内容 |
+| `frontend/src/core/artifacts/hooks.ts` | TanStack React Query hook，5 分钟缓存 |
+| `frontend/src/components/workspace/artifacts/context.tsx` | ArtifactsProvider + useArtifacts() — 管理列表、选中、开关、自动选中 |
+| `frontend/src/components/workspace/artifacts/artifact-file-detail.tsx` | 产物详情视图：头部(文件选择器+code/preview切换) + CodeEditor/Preview |
+| `frontend/src/components/workspace/artifacts/artifact-file-list.tsx` | 卡片式列表视图，每个卡片含图标/名称/扩展名/下载/安装按钮 |
+| `frontend/src/components/workspace/artifacts/artifact-trigger.tsx` | 头部触发按钮，仅在产物存在时显示 |
+
+#### 前端渲染
+
+| 文件 | 职责 |
+|------|------|
+| `frontend/src/components/workspace/code-editor.tsx` | CodeMirror 只读编辑器，支持 CSS/HTML/JS/JSON/MD/Python 语法高亮 |
+| `frontend/src/components/ai-elements/code-block.tsx` | Shiki 语法高亮代码块，双主题(light/dark) |
+| `frontend/src/components/ai-elements/web-preview.tsx` | iframe 网页预览，含地址栏和导航按钮 |
+| `frontend/src/components/workspace/messages/markdown-content.tsx` | Streamdown 渲染 Markdown (GFM + Math + Raw HTML + KaTeX) |
+| `frontend/src/core/utils/files.tsx` | 140+ 扩展名→语言映射，文件图标/类型判断 |
+
+#### 后端
+
+| 文件 | 职责 |
+|------|------|
+| `backend/.../thread_state.py` | ThreadState.artifacts 列表 + merge_artifacts 去重 reducer |
+| `backend/.../present_file_tool.py` | present_files 工具 — 标准化路径，返回 Command(update) |
+| `backend/.../paths.py` | 路径管理：threads/{id}/user-data/{workspace,uploads,outputs} |
+| `backend/app/gateway/routers/artifacts.py` | FastAPI 路由：GET 产物文件，MIME 检测，安全处理 |
+
+### 1.3 支持的内容类型
+
+| 类型 | 渲染方式 |
+|------|----------|
+| 代码文件 (140+ 扩展名) | CodeMirror 只读 + 语法高亮 |
+| Markdown (.md) | Streamdown (GFM + Math + KaTeX + Raw HTML) |
+| HTML (.html/.htm) | 沙箱 `<iframe>` (srcDoc) |
+| 图片 (.png/.jpg/.svg/.webp) | `<img>` 标签，非代码文件用 iframe |
+| .skill 压缩包 | ZIP 解压，SKILL.md 渲染为 Markdown |
+| 二进制文件 (PDF 等) | 后端 inline Content-Disposition |
+| 文本文件 (.txt/.csv/.log) | CodeMirror 纯文本模式 |
+
+### 1.4 持久化架构
+
+**磁盘存储：**
+```
+{DEER_FLOW_HOME}/threads/{thread_id}/user-data/outputs/
+```
+
+**状态持久化：** artifacts 列表是 LangGraph ThreadState 的一部分，由 checkpoint 系统自动持久化。
+
+**前端缓存：** TanStack React Query，5 分钟 stale time。
+
+### 1.5 UI/UX 设计模式
+
+#### 分栏布局 (chat-box.tsx)
+- `react-resizable-panels` 水平分栏
+- 关闭态：chat=100%, artifacts=0%
+- 打开态：chat=60%, artifacts=40%
+- 300ms CSS 过渡动画
+
+#### 自动打开 + 自动选中
+- 检测到 `write_file` / `str_replace` tool call 时自动打开面板并选中文件
+- `autoOpen` / `autoSelect` 标志防止用户手动关闭后重复打开
+
+#### 代码/预览切换
+- HTML/Markdown 默认 Preview，其他默认 Code
+- Preview 用 Streamdown(MD) 或 iframe(HTML)
+
+#### 头部操作栏
+- 文件选择器下拉菜单（不用返回列表即可切换）
+- 复制 / 下载 / 新窗口打开 / 关闭
+
+#### 聊天内嵌展示
+- `present_files` tool call → 聊天流内渲染卡片网格
+- 点击卡片 → 侧栏打开该文件
+
+#### 双路径方案
+1. **真实文件路径** — 从后端 API 获取，React Query 缓存
+2. **`write-file:` 虚拟路径** — 直接从 tool call args 提取内容，无需后端请求，支持流式显示
+
+### 1.6 Provider 层级
+
+```
+ArtifactsProvider → 提供useArtifacts() context
+  ChatBox → ResizablePanelGroup
+    Panel(chat) → MessageList → ToolCall 自动打开产物面板
+    Panel(artifacts) → ArtifactFileDetail → useArtifactContent() hook
+```
+
+---
+
+## 二、Hermes Agent 产物机制
+
+> **结论：Hermes Agent 无产物面板、无 Web 前端、无分栏布局。** 它是终端 CLI 工具，所有输出在终端内联渲染。但有值得借鉴的大输出处理机制。
+
+### 2.1 项目定位
+
+Hermes Agent 是 **Python CLI/TUI Agent**（类似 Claude Code），通过 prompt_toolkit TUI 运行，同时支持 Telegram/Discord/Slack/WhatsApp 等 IM 平台网关。
+
+**无 React/Next.js/Web UI。** 暴露 OpenAI 兼容 API 供 Open WebUI/LobeChat 等第三方 UI 接入。
+
+### 2.2 大输出处理（3 层防御）
+
+这是唯一接近"产物管理"的机制，值得借鉴。
+
+**文件：`tools/tool_result_storage.py`**
+
+| 层级 | 机制 | 说明 |
+|------|------|------|
+| Layer 1 | 工具自身截断 | 每个工具限制自己的输出长度 |
+| Layer 2 | `maybe_persist_tool_result` | 单个结果超阈值 → 写入沙箱临时文件，上下文中替换为 `<persisted-output>` 预览块 |
+| Layer 3 | `enforce_turn_budget` | 整轮超过 200K 字符 → 最大的几个溢出到磁盘 |
+
+核心逻辑：
+```python
+# 超阈值时：完整内容写入文件，上下文替换为预览
+remote_path = f"{storage_dir}/{tool_use_id}.txt"
+_write_to_sandbox(content, remote_path, env)
+return _build_persisted_message(preview, has_more, len(content), remote_path)
+# 后续 agent 可用 read_file + offset/limit 读取完整内容
+```
+
+### 2.3 预算配置
+
+**文件：`tools/budget_config.py`**
+
+| 参数 | 默认值 |
+|------|--------|
+| `DEFAULT_RESULT_SIZE_CHARS` | 100,000（单工具阈值）|
+| `DEFAULT_TURN_BUDGET_CHARS` | 200,000（整轮上限）|
+| `DEFAULT_PREVIEW_SIZE_CHARS` | 1,500（内联预览长度）|
+
+### 2.4 CLI 渲染方式
+
+**文件：`agent/display.py`**
+
+- **工具进度**：KawaiiSpinner 动画 + 一行摘要
+- **文件编辑**：内联 colored unified diff（write_file / patch 工具）
+- **最终响应**：Rich Panel 边框包裹，主题色可换（7 套 skin）
+
+### 2.5 会话持久化
+
+**文件：`hermes_state.py`**
+
+SQLite (`~/.hermes/state.db`) + FTS5 全文搜索：
+- sessions 表：元数据、模型配置、token 计数、费用、标题
+- messages 表：role、content、tool_call_id、reasoning、时间戳
+
+### 2.6 值得借鉴的点
+
+| 点 | 借鉴价值 |
+|----|----------|
+| 大输出溢出到磁盘 + 内联预览 | 解决 context window 溢出问题 |
+| 3 层递进防御 | 对 ZCLAW 中间件链有参考价值 |
+| 预算配置化 | 阈值可调，不同场景不同策略 |
+
+---
+
+## 三、对比分析：ZCLAW 现状 vs 参考方案
+
+### 3.1 现状差距
+
+| 维度 | DeerFlow | ZCLAW 现状 | 差距 |
+|------|----------|------------|------|
+| 数据源 | 3 个工具(present_files/write_file/str_replace)主动注册 | 仅 streamStore 解析 tool output 的 filePath | 极窄，几乎不触发 |
+| 持久化 | 磁盘文件 + LangGraph checkpoint | 纯内存 Zustand | 刷新即丢失 |
+| 渲染-代码 | CodeMirror 只读 + 语法高亮 (140+ 语言) | 纯 `<pre>` 标签，无高亮 | 无高亮 |
+| 渲染-Markdown | Streamdown (GFM+Math+KaTeX+RawHTML) | 手写 30 行正则渲染器 | 仅标题/粗体/列表 |
+| 渲染-HTML | 沙箱 iframe | 不支持 | 无 |
+| 渲染-图片 | `<img>` + iframe | 类型声明了无实现 | 无 |
+| 渲染-表格 | GFM 表格 | 纯文本 `<pre>` | 无 |
+| 面板布局 | react-resizable-panels 60/40 | react-resizable-panels 65/35 | 已有，可复用 |
+| 自动打开 | write_file/str_replace 触发 | addArtifact 时打开 | 已有 |
+| 文件选择 | 下拉菜单不离开详情视图 | 必须返回列表再选 | 体验差 |
+| 聊天内嵌 | present_files → 卡片网格 | 无 | 缺失 |
+| 缓存 | React Query 5min | 无 | 缺失 |
+| 双路径 | 真实路径 + write-file: 虚拟路径 | 仅运行时内存 | 缺失 |
+| 右面板重叠 | 单一面板 | ArtifactPanel + RightPanel"文件"tab 职责交叉 | 架构问题 |
+
+### 3.2 核心差距总结
+
+**按优先级排列：**
+
+1. **P0 数据源断裂** — 产物几乎没有来源，是最根本的问题
+2. **P0 无持久化** — 产物刷新即丢
+3. **P1 Markdown 渲染残缺** — 30 行正则 vs 完整 GFM 渲染器
+4. **P1 代码无语法高亮** — 纯 `<pre>` vs CodeMirror/Shiki
+5. **P2 双面板职责交叉** — ArtifactPanel vs RightPanel"文件"tab
+6. **P2 缺少详情内文件切换** — 需返回列表才能切换文件
+7. **P3 聊天内嵌产物卡片缺失**
+8. **P3 HTML/图片/表格渲染缺失**
+
+### 3.3 推荐方案
+
+#### 方案 A：最小可行（基于现有架构补全）
+
+在现有 ArtifactPanel + artifactStore 上修补：
+
+- **数据源**：扩展 streamStore 中的 tool output 解析，覆盖更多工具类型
+- **持久化**：artifactStore 追加 IndexedDB 写入（复用 messageStore 模式）
+- **Markdown**：引入 `react-markdown` + `remark-gfm` 替换手写渲染器
+- **代码高亮**：引入 `shiki` 或 `highlight.js`
+- **合并面板**：RightPanel "文件"tab 功能合并到 ArtifactPanel，删除 RightPanel 的 files tab
+
+**工作量**：~2-3 天
+
+#### 方案 B：参照 DeerFlow 重构（推荐）
+
+借鉴 DeerFlow 架构但适配 ZCLAW Tauri 本地架构：
+
+| DeerFlow 组件 | ZCLAW 适配 |
+|---------------|------------|
+| FastAPI 产物路由 | Tauri 命令 `artifact_list` / `artifact_read` / `artifact_serve` |
+| 磁盘 outputs/ 目录 | `{workspace}/artifacts/{session_key}/` |
+| LangGraph checkpoint | SQLite (已有 zclaw-memory) |
+| React Query 缓存 | TanStack Query 或 Zustand + stale cache |
+| CodeMirror 只读 | 引入 @uiw/react-codemirror |
+| Streamdown MD | react-markdown + remark-gfm + rehype-katex |
+| iframe HTML 预览 | Tauri webview window (安全隔离) |
+
+**核心改动清单：**
+
+1. **Rust 侧**（zclaw-kernel）：
+   - 新增 `artifact_create` / `artifact_list` / `artifact_read` Tauri 命令
+   - 产物写入 `{workspace}/artifacts/{session_key}/`
+   - 中间件链中 ToolEnd 事件触发产物注册
+
+2. **前端 Store**：
+   - artifactStore 增加 IndexedDB 持久化
+   - 从 streamStore 解耦产物创建逻辑到独立 hook
+
+3. **前端组件**：
+   - 替换 MarkdownPreview → react-markdown + GFM
+   - 引入 CodeMirror/shiki 代码高亮
+   - 详情视图增加文件下拉切换
+   - RightPanel "文件" tab 合并或移除
+
+**工作量**：~5-7 天
+
+#### 方案 C：借鉴 Hermes 防御机制（附加）
+
+无论选 A 还是 B，都可叠加 Hermes 的大输出防御：
+
+- 中间件链 ToolOutputGuard 层增加溢出检测
+- 超阈值产物自动持久化到磁盘，上下文替换为 `<persisted-output>` 预览
+- agent 可通过 read_file 回读完整内容
