Add initial Hugo landing page

First pass at the tidyindex.com marketing site, built with a custom
minimal Hugo theme — light palette (white/soft blue), Inter + JetBrains
Mono, hero with a JSON code preview, format/audience/value sections,
and a single-button CTA. Also adds a top-level .gitignore for local
Claude/IDE state.
