docs: fix README consumer on-ramp (host + fonts); fold tracking into WP-0003 T06

- README: correct the Node-tooled install host (placeholder gitea.example.com →
  gitea.coulomb.social/coulomb/whynot-design) and rewrite the Type/font prose to
  match the actual tokens (system font stacks, no webfont; Plex kept as history).
- WHYNOT-WP-0003 T06: add a "Tracking whynot-design from a consuming repo" README
  section (pin → inspect → drift → adopt) and reconcile the install pin once
  T01/T02 publish a tag.
- Record the README fixes as ADHOC-2026-06-27.
