feat: list each declared doc kind as its own homepage card

- compute per-kind home URLs (lib/, api/, wiki/) via _find_home_for_kind
- emit one card per declared kind so multi-kind repos (e.g. doc-forge
  with lib + wiki) appear in each matching homepage section
- declare the doc-forge wiki kind and refresh its vendored site with the
  combined lib + wiki build
