Convert all documentation links to repo-relative format (/docs/path/file.md)
so they work when browsing on GitHub. The rehype plugin strips /docs/ prefix
and converts .md to trailing slash at build time for Astro/Starlight.
- Update rehype-markdown-links.js to strip /docs/ prefix from absolute paths
- Update fix-doc-links.js to generate /docs/ prefixed paths with .md extension
- Convert 217 links across 64 files to new format
