feat(identity): source-aware short-drama enrichment with snippet mode and hit rate (META-2)
- classify enrich sources: encyclopedia, platform pages (hongguo, kuaikaw, video platforms), douban (search snippet only) and other sites' search snippets (snippet mode, pages never opened); one extractor per source, fields carry source kind and confidence, merged by noisy-OR across hosts - new cast field (applied as MediaCredit with placeholder ids) - robots.txt check (cached per host 1 day) and login-wall/captcha give-up - per-enrichment source attempts + GET /identity/enrich-stats, 30-day hit-rate table under settings -> metadata -> identity - setting identity.enrichSnippetAllSites (default on); default domains add baike.com and kuaikaw.cn - replay fixtures from the real run on the 4 user-library short dramas (sanitized Brave responses, hongguo page, robots.txt) Co-Authored-By: Claude Opus 5.5 <[email protected]>
