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.
