• Keep regular version updates in versions.mk only.
• Keep workflow changes in .github/workflows/release.yml only.
• Change libs/*/build.sh only when upstream changes break builds.

Push a v* tag to run .github/workflows/release.yml and publish a GitHub Release. GitHub Actions versions are maintained by Dependabot.
