fix(seo): canonical self-deindexing on /docs/*, truthful llms.txt, real sitemap dates, RSS feed, breadcrumbs, per-article OG images

- /docs subpages canonicalized to /docs and had no descriptions; each now
  uses pageMetadata with its own path (was: Google could index at most one)
- llms.txt claimed Team EUR 149, RBAC/SLA and BYO-cloud that do not exist;
  regenerated from lib/seo.ts truth + new llms-full.txt with docs content
- sitemap stamped lastModified=now on every request; now real per-route dates
  from new lib/articles.ts registry (single source for guides index/sitemap/RSS)
- new /feed.xml RSS 2.0 route + alternates link in root layout
- articleJsonLd: image (per-guide opengraph-image via lib/og-article.tsx),
  Person author, wordCount; new breadcrumbJsonLd on guides + docs
- GSC verification via NEXT_PUBLIC_GSC_VERIFICATION (documented in .env.example)
- dropped fabricated Enterprise EUR 499 offer from SoftwareApplication JSON-LD
- article-shell: OL/Table/Note primitives for upcoming articles
