v1.4.0 修复反爬误判+浏览器崩溃空转, 详情页多元翻页

- 修复反爬误判: is_challenge_page 仅匹配 title 关键词 + html 前 20KB 强特征标记,
  不再全文匹配 captcha/challenge 等词 (博客园正文提 captcha 的页面被误杀)
- 修复浏览器崩溃后空转: 检测 Target page/context/browser closed,
  自动重启浏览器并重试当前 URL (不消耗重试配额, 单页最多重建3次);
  页面读取连续异常3次快速失败; 新增 browser_max_pages 配置定期重启浏览器防内存膨胀
- 详情页多元翻页: 首页/末页/页码列表(带省略号)/页码跳转输入框(回车/GO)/每页条数选择(50/100/200/500)
