feat(curation): auto-curation after crawl + quality messaging

Automate curation:
- Add runPostCrawlCuration() to DB queries — runs after every
  full and incremental crawl (classify, dedup, category counts)
- No more need for manual curate.mjs runs after each crawl

Quality messaging:
- Homepage stats label: "Skills" → "Curated Skills" (en/fa)
- Add curation note: "deduplicated and quality-filtered from X+ repos"
- Update fallback counts from 172K to 16K across all touchpoints
  (BetaBanner, getting-started prompts, email templates)
- getting-started skill count query now uses browse-ready filter
