Changed image naming scheme from separate builder/runtime images to a single image name with different tags: - docker.io/gmcintire/towerops-base:builder - docker.io/gmcintire/towerops-base:runtime - docker.io/gmcintire/towerops-base:latest (alias for runtime) This simplifies the naming and makes it clearer that both images are part of the same towerops-base image family. Changes: - build.sh: Use IMAGE_NAME with BUILDER_TAG/RUNTIME_TAG - Makefile: Update all targets to use new naming - k8s/Dockerfile: Point to gmcintire/towerops-base:builder and :runtime
