feat: 添加图片搜索功能和 Qwen 模型支持
图片搜索功能（以图搜图）： - Chatwoot webhook 检测图片搜索消息 (content_type="search_image") - 从 content_attributes.url 提取图片 URL - 调用 Mall API 图片搜索接口 (/mall/api/spu?searchImageUrl=...) - 支持嵌套和顶层 URL 位置提取 - Product Agent 添加 fast path 直接调用图片搜索工具 - 防止无限循环（使用后清除 context.image_search_url） Qwen 模型支持： - 添加 LLM provider 选择（zhipu/qwen） - 实现 QwenLLMClient 类（基于 DashScope SDK） - 添加 dashscope>=1.14.0 依赖 - 修复 API key 设置（直接设置 dashscope.api_key） - 更新 .env.example 和 docker-compose.yml 配置 其他优化： - 重构 Chatwoot 集成代码（删除冗余） - 优化 Product Agent prompt - 增强 Customer Service Agent 多语言支持 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
