Rewrite repo-RELATIVE markdown links (](../../doc/x.md), ](./y)) to absolute GitHub blob URLs so a
README harvested into the site doesn't ship dead links. relDir is the package's path from the repo root
(e.g. tooling/ts/packages/core); the link is resolved against it and normalized. Absolute links
(http(s):, mailto:, protocol-relative), pure #anchors, and already-absolute paths are left untouched.
