docs(site): homepage hero, metadata, and closing CTA on the new positioning

Align the docs-site homepage with the merged README: hero becomes 'A
complete business system in 16k tokens.' with the business-ontology
framing, page <title>/description follow, and the closing CTA states the
build & ask with Claude Code vs online (ObjectOS) split. Empty changeset —
site copy only, releases nothing.
