Enhanced base image build system with: Container Engine Support: - Auto-detect podman or docker (prefers podman if both installed) - All scripts work with either engine seamlessly - No configuration needed Docker Hub Integration: - Push to both GitLab and Docker Hub registries - GitLab: registry.gitlab.com/towerops/towerops/elixir-runtime - Docker Hub: docker.io/gmcintire/elixir-runtime - Both versioned and :latest tags pushed to each Build Script: - Detect and use $CONTAINER_CMD for all operations - Show which container engine is being used in output - Tag and push to both registries automatically Makefile: - Add CONTAINER_CMD variable with auto-detection - Add DOCKERHUB_REGISTRY configuration - Update all targets to use detected container engine - Add login-dockerhub target for Docker Hub authentication - Update push target to push to both registries Documentation: - Document podman/docker auto-detection - Update login instructions for both registries - Update troubleshooting with examples for both engines This makes the build system more flexible and accessible to users who prefer podman over docker, while also publishing to the public Docker Hub registry for easier access.
