Fix: root index.html (the actual main page) updated to v3.6

The root / is served by docs/public/index.html (not welcome.html).
This file still had all v3.5-alpha6 references. Updated:
- SEO/meta/JSON-LD ontology links to v3.6
- Nav: Spec->Docs, Browse->/browse/index.html, Ontology->v3.6
- CTA: Read the Spec -> Read the Docs
- ai:protocol meta tag fixed (was v3.6-alpha6 artifact)
