Scaffold flagship v3 site at / with new sections…

Details

Introduce a third site version ("v3") as the new flagship at /, relocating
v2 to /v2/ and keeping v1 at /v1/. v3 reuses the signature animated canvas
backgrounds and the three floating glass toggles verbatim by stable id.
New, research-informed sections and features:
- sharpened hero with a single CTA hierarchy + status pill
- affiliation/venue social-proof strip and a dated "Now" panel
- quantified-impact animated stats (counts from Supabase)
- interactive NeuroSymbolic explainer (canvas; reduced-motion fallback)
- selected-publications renderer with venue/year/award badges + link rows
- featured projects gallery with named tooling tags
- command palette (⌘K) with keyboard nav, focus trap, version switch
- copy-email button, JSON-LD Person schema + OG/Twitter cards, console egg
Cross-version switcher: v3 links to v2/v1; v2 gains a "Latest site" link
while keeping its v1 link. db:// masking and /view.html are unchanged.
