kuma

Backport a merged kumahq/kuma PR to release branches end-to-end — trigger the backport workflow if needed, find the generated backport PRs, resolve cherry-pick conflicts (module-path rewrites, older APIs), fix DCO, build+test per branch, force-push, clean up PR descriptions/labels, mark ready, and watch CI. Use whenever the user gives a kuma PR link and mentions backporting, backport PRs, cherry-pick conflicts on release-X.Y branches, or asks to fix CI on chore/backport-* PRs.
