Root cause: act_runner provides minimal environment without sudo
or Docker CLI. Cannot install packages in workflow.
Solution: Use docker:24-dind container which includes Docker CLI
and daemon. Runs with --privileged to allow nested containers.
Changes:
- Use docker:24-dind as job container
- Remove installation steps (Docker pre-installed)
- Keep simple login, build, push workflow
Also added alternative solution file showing how to configure
runner with Docker CLI for better performance.
