fix(landing): complete Organization schema, add CollectionPage/BlogPosting JSON-LD, fix TechArticle rich-result eligibility

- Organization schema (site-structured-data.tsx): add brand and
  contactPoint.url (verified against the real /contact route); all other
  fields were already correct and verified against the Footer's sameAs
  links. foundingDate/legalName/address omitted — not verifiable from
  anything in this repo.
- CollectionPage (blog + library index): buildCollectionPageJsonLd now
  takes the real posts list (same getAllPostMeta() the index page already
  renders from) and emits a mainEntity ItemList of BlogPosting stubs
  instead of omitting mainEntity entirely.
- BlogPosting + TechArticle (post detail template): Google's Article
  rich-result eligibility only recognizes Article/NewsArticle/BlogPosting
  — a bare TechArticle type isn't in that allowlist. buildArticleJsonLd
  now emits a multi-type @type array (["BlogPosting","TechArticle"]) for
  genuinely technical posts, and "BlogPosting" alone for posts that are
  general announcements, via a new `technical` frontmatter flag (defaults
  true; set to false on the series-a funding-announcement post, the one
  post with no technical content). Also fixed a real markup/schema
  mismatch: the article's `speakable.cssSelector` referenced
  `[itemprop="description"]`, but no element carried that itemProp —
  added it to the description paragraph. TechArticle/BlogPosting image
  URLs are now made absolute (previously relative paths, invalid for
  crawlers).
- FAQPage: audited every LandingFAQ usage (/models, /models/[provider],
  /models/[provider]/[model], /integrations, /integrations/[slug],
  /comparison, /comparison/[provider]) — all already emit matching
  FAQPage JSON-LD sourced from the same data passed to LandingFAQ; no
  gaps found, no changes needed.
