DEFAULT_ACTIONS_URL=self requires local actions use short form

git push --tags fails on protected main branch since the runner's

bypasses branch protection. Also removes unnecessary VERSION file
commit since CalVer is derived from tags.

act_runner cache server. Registry-based caching stores layers on
Docker Hub, which is more reliable for self-hosted runners.
