docs: drop ANSI block-letter banner, add npm install + landing-page install section

- README: removed the ASCII 3D 'DHAMAKA' fallback (didn't render well), added
  the npm install one-liner and shields.io badges right under the SVG banner,
  split the quickstart into 'just want to use the SDK?' (npm install) and
  'want to hack on the runtime?' (clone + build.sh).
- Playground landing page: added an Install section with the npm command,
  a minimal SmartField snippet, and links to npm + GitHub Packages.
