feat(sites): structure release detail pages and rework the detail drawer (DETAIL-1)

Adapters (pure functions + tests):
- detail-description: strip HTML/BBCode residue, drop site template blocks and
  ad/signature lines (configurable rules), parse PT info blocks (◎ / 【】 / 『』 /
  「键:」) into infoBlock and body paragraphs
- mediainfo: MediaInfo and BDInfo (quick summary + full report) into a summary
  of container/duration/bitrate/size, video (HDR/DV), audio and subtitle tracks
- file-tree: file list into a flattened directory tree with sizes and
  main/sample/subtitle/extra roles
- formatDetailPage combines them; the server computes it when reading the
  cached detail page, so existing caches benefit without a refetch

Contracts: SiteReleasePage gains infoBlock, paragraphs, media, fileTree.

Web: drawer now reads top-down: meta row (promo/H&R, size, peers, upload time,
IMDb/TMDB/豆瓣 tags) → 资料 → 简介 (collapsible) → 技术规格 (raw folded) →
截图 grid with keyboard lightbox → 文件 tree; inventory overlay moved into the
fixed footer next to 下载.

Fixtures: 6 desensitized samples from the local cache (site.detail and RSS
descriptions) plus synthetic multi-track MediaInfo, BDInfo, bracket blocks and
directory file lists.
