GitHub release cadence & history API

Folds a repo's GitHub release list into a release-cadence intelligence card: stable-vs-prerelease counts, the latest stable release, days since it shipped, the MEDIAN gap between stable releases, a cadence label (rapid/steady/occasional/slow), and the 10 most recent releases. Answers 'how often does owner/repo ship', 'when was the last stable release', 'is this project releasing rapidly or stalled'.
