hz4th_coder 56f30f78c4 新增打包导出: 任务输出目录打包为 zip, 支持网页下载或发送到指定邮箱(默认 wlq@tphai.com)
- GET /api/export?task_id= 打包输出目录为 zip 并下载 (zip 内按任务名建顶层目录)
- POST /api/export/email 打包后通过 send_email.py 发送附件到邮箱, 邮箱可指定, 默认 wlq@tphai.com
- 详情弹窗新增 [📦 打包下载] [📧 发邮箱] 按钮, 打包中按钮禁用防重复点击
- notify.py 重构: send_attachment(subject, body, to, attach) 通用附件发送
- 打包文件存 data/exports/, 自动清理只保留最近 10 个
- 实测: cnblogs-auto 66MB/1606文件 -> 11.9MB zip 仅1.5s; 邮件发送成功 2.2s

hz4th_coder 0482284cc0 反爬拦截不再重试: 判定为反爬类错误(403/429/503/Cloudflare/captcha/验证页等)直接放弃该页, 节省重试时间; 验证页持续8秒即判定反爬, 不再干等满超时(默认60s)
- engine.is_anti_crawl_error: 反爬错误信号关键词判定
- _retry_crawl: 反爬错误直接 break, entry.error 标注'反爬拦截, 跳过重试'
- _wait_page_settle/_settle_wait: 连续8秒检测到验证页即判定反爬尽早返回
- 集成测试: 反爬页 attempts=1 且 8.1s 放弃; 非反爬错误仍 attempts=retry_count+1 正常重试
