feat(docs): landing page at / + self-hosted logo assets (#3088)

The objectstack.ai marketing site is being retired (repo archived, domain
will 301 here), making the docs site the project homepage:

- `/` now renders a one-screen hero (get started / documentation / GitHub
  + ObjectOS cross-link) instead of redirecting to /docs
- nav logo + favicon served from public/ instead of hot-linking
  https://objectstack.ai — that URL already 500s today, so the nav logo
  and favicon were broken in production
- top nav gains Docs / Blog links (visible on the HomeLayout pages)
- drop the now-unused objectstack.ai images.remotePatterns entry
