Subject: [PATCH] feat: make Surplus visible and connected across the product
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add "Surplus × Zetta" to the Solutions nav dropdown so the page
  is discoverable from every product page
- Add "View full Surplus report →" banner in the inference tab on
  registry profiles when inference activity exists — bridges the
  registry to /surplus/[slug] automatically
- Fix @zettatracker → @zettaaidotco on the /surplus landing page CTA
