make-release-desc.sh now emits "Changelog since [vX.Y.Z](<repo>/releases/tag/vX.Y.Z)"
instead of a plain version string, so the release notes link back to the previous release.
The repo URL is derived from the origin remote (SSH or HTTPS); if it cannot be
resolved (local run without origin), the title falls back to plain text.
