fix(sites): normalize HHClub RSS items, complete detail page parsing (HH-2)

- RSS: split NexusPHP "[category]name[subtitle][size][uploader]" titles in the
  site adapter layer (category id/name/media type, clean title, subtitle,
  size); snapshot fields win on merge; lazily renormalize old RSS rows and
  re-emit release.observed; unknown list fields show an em dash
- Detail: HHClub section layout (douban info block as description,
  screenshots section, IMDb/TMDB from MediaInfo lines, upload time field,
  on-demand viewfilelist.php once); site CDN screenshots get a Referer
- Site request count now includes site-bound RSS fetches
- Origin view shows "自动化" when idle and "Agent" only after recent
  automation actions (lastAutomationAt); agent step titles no longer get
  squeezed to a sliver by long notes
