v2.0.1 修复搜索并发冲突与提交失败问题

- 搜索服务改用 namespace 隔离浏览器实例（参考 webtest-agent 方案），
  解决定时任务与手动处理并发调用 agent-browser 互相踢掉导致搜索结果为0的问题
- agent-browser 调用加瞬时错误自动重试，使用 /tmp/xdg-rt 目录
- 步骤4 提示词放宽：品牌/系列相关页面也纳入提取，无精确型号时兜底选最相关内容
- 步骤4 大模型返回空时自动兜底，不再直接跳过导致会话卡死
- 会话收尾修复：失败/无数据时会话状态正确标记，并自动移除待处理产品
- 处理入口统一：定时任务/单产品/批量处理均改为 process_monitor 大模型流程（防重）
- paramhub_client 增加登录态自动恢复：401 或连接失败时自动重新登录重试
- 全流程实测通过：deepseek-v4-flash-0731 → review_id 19ed2daaabfe
