Pull Request Overview

This PR updates CI scripts to use the latest base image dynamically and groups key steps in GitHub Actions logs.

• Emit the GenAIComps commit hash and build a configurable comps-base image.
• Wrap CI phases (stop, build, start, validate, prune) in ::group::/::endgroup:: markers.
• Add IMAGE_REPO and BASE_TAG build args in build.yaml and make FROM dynamic in the Dockerfile.

• [nitpick] Consider adding IMAGE_REPO and BASE_TAG build arguments to other service definitions (e.g., translation-ui, llm-textgen) so they can also pull from the intended base image repository.

IMAGE_REPO: ${REGISTRY:-opea}

• [nitpick] It may be clearer to wrap docker system prune -f in its own ::group::/::endgroup:: block to keep its logs isolated and improve readability.

docker system prune -f

• [nitpick] The sleep 1s after the build may be too short for all processes to settle—consider aligning it with the existing sleep 3s used after docker images to ensure stability.
