新增按需截图功能：滚动截图 + 视觉大模型实时判断

- 新 action=smart：每次截图后用视觉大模型判断主题内容是否已截全、是否还需向下滚动，自动滚动到判定完成，最后纵向拼接成长图 - 默认视觉模型 qwen3.6-plus（autodl），支持 agent-browser / playwright 双后端 - LLM 接口可网页配置：⚙️智能配置弹窗(base_url/api_key/model/提示词/最大滚动次数/滚动比例/超时) + 测试连接 + 持久化到 data/config.json - 新增 API：GET/POST /api/smart/config、POST /api/smart/test - 安全兜底：大模型判断失败保守停止、滚动位置不再变化判底部、最大滚动次数上限 - 历史新增 smart 类型：入库拼接长图+AI判断过程日志，详情弹窗可查看每一步截图判断 - 前端：智能模式提示条 + 结果展示拼接长图 + AI判断过程折叠查看 + 历史筛选/徽章/详情
新增可读文本提取 + 历史记录分页管理

 # 手动 Chrome 捕获指南
 ## 方案三完整流程
 ### 1️⃣ 启动真实 Chrome（带调试端口）
 在您的本地机器或服务器上运行：
 ```bash
 # Linux
 google-chrome --remote-debugging-port=9222 https://www.techpowerup.com/gpu-specs/rtx-pro-6000-blackwell.c4272
 # 或者使用已有的 Chrome 进程（需要先关闭所有 Chrome）
 google-chrome-stable --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug
 ```
 ### 2️⃣ 手动验证（如 Cloudflare）
 - 在浏览器中手动完成验证过程
 - 等待页面完全加载
 - 确认可以看到正常内容
 ### 3️⃣ 连接到 Chrome 并截图
 验证完成后，运行脚本：
 ```bash
 # 连接到 Chrome 并截图
 python3.12 /tmp/connect_chrome.py techpowerup
 # 或者捕获当前所有页面
 python3.12 /tmp/connect_chrome.py
 ```
 ### 4️⃣ 查看结果
 ```bash
 # 查看截图
 ls -lh /tmp/chrome_capture_*.png
 # 查看HTML
 head -100 /tmp/chrome_html_0.html
 ```
 ## API 集成方案
 如果需要通过 API 获取内容，可以：
 1. 在服务代码中添加 CDP 连接选项
 2. 用户先手动验证
 3. API 连接到已验证的浏览器实例
 ## 注意事项
 ⚠️ **重要**：
 - Chrome 必须带 `--remote-debugging-port=9222` 启动
 - 所有 Chrome 进程必须先关闭（或使用新的 user-data-dir）
 - 验证完成后才能运行脚本
 - 截图后浏览器保持打开，可以继续使用
 ## 一键脚本
 ```bash
 # 启动 Chrome 并等待用户验证
 google-chrome --remote-debugging-port=9222 "https://www.techpowerup.com/gpu-specs/rtx-pro-6000-blackwell.c4272" &
 echo "请在浏览器中完成验证，然后按 Enter 继续截图..."
