fix(adapters): 观众详情页按真实页面适配(DET-2)

- 促销:详情 h1 是 font.free / font.halfdown 等 + 剩余时间 span[title],新增 umt.detail.promo 覆盖列表促销字段(以前一律判成无促销并覆盖列表的免费)
- 标题去掉 h1 里的「剩余时间：」;发布时间不再取标题区的促销到期时间
- 做种 / 下载 / 完成数、种子 Hash:umt.detail.fields.seeders / leechers / snatched / infoHash
- 副标题去掉评分徽标;标签只取最内层;上传者取 span.torrent-uploader-wrap,标签精确匹配(避开「发布者带宽」)
- 简介:去掉站点声明(page.descriptionStrip)与 MediaInfo 控件(codetop / show / hide),源码换行不再算一行
- 截图排除豆瓣海报与站点横幅
- 列表副标题改取 span.torrent-subtitle-text(以前前面粘着标签文字)
- 脱敏真实样本:详情 2 页进 differential/detail.test.ts,列表 1 页进 MP 差分
