feat: implement config-driven link page

Single-page link-in-bio site at config.yaml -> build.js -> _site/index.html.
Links flagged with `repo: owner/name` get live star count and last-commit
age decoration from the GitHub REST API at build time.

Stack: vanilla HTML/CSS output, Node 20 build script (sole dep: js-yaml).
Deploy: GitHub Actions Pages artifact, daily cron + push triggers.

Architecture inspired by linkyee (MIT); no source code copied. See NOTICE.
