refactor(ci): call release composite actions from release.yml

Replace the inline bodies of binaries, veans-binaries, os-package, and
veans-os-package jobs with calls to the new release-binaries and
release-os-package composite actions. Each call site is now ~25 lines
of inputs instead of ~75 lines of duplicated mage+upx+gpg+s3 plumbing.

publish-repos switches from the parent's ./mage-static to the
prebuilt build_mage_bin artifact so it can drive build/'s repo metadata
targets inside the publish-repos containers.
