Epic: NameKit

[lightwalker-eth]

Key goals:

• Rebrand ensnode-react into namekit
• Build a new Identity UI component strategy that can deliver the world's best DX and UX for loading ENS identity data.
• Create a new landing page for https://www.namekit.io/ (for now, implemented as a new "docs" site in the ENSNode monorepo)
  • Rebrand "NameKit" as the best UI-component library for building on ENS. Compare with the branding of wagmi (which builds on viem) vs viem.
  • Sunset the existing NameKit landing page and brand.
