feat(site): go.dev-style homepage + shared nav/footer chrome
- wo-html grows generic nav_bar/card/btn_link + the utility classes
they need (sticky nav, footer, 2-col grid, hero sizes); library
stays content-free
- home: hero (tagline + Get started/View source CTAs), real actor+
table code showcase, four why-cards, chapters strip (gate's
'Learn writeonce' anchor kept); every page shares nav + footer
- site gate 11/0 unchanged; loopback bind untouched
