Rebrand · GitHub URLs and install command to nutlope/hallmark

Repo handover prep. Replaces:
- github.com/Luffixos/hallmark → github.com/nutlope/hallmark
  (banner star link, footer link, JS REPO constant for star count)
- npx skills add hallmark → npx skills add nutlope/hallmark
  (README install section, four install panes in site/index.html)

No skill internals touched — SKILL.md and references/ unchanged.
The local installed skill at ~/.claude/skills/hallmark/ continues
to work; the URL change is content-only.
