  test-unit           - Execute unit test suite with pytest
  helm-package         - Package the LightRAG Helm chart (version: $(CHART_VERSION))
  helm-push            - Package and push the chart to $(HELM_REGISTRY)
  clean                - Remove packaged charts from $(CHART_PACKAGE_DIR)
  hooks-build          - Build the pre-commit hooks image $(HOOKS_BUILD_IMAGE)
  hooks-publish        - Build and push the hooks image to its registry

Set VERSION=1.2.3 to override the git-derived chart version.
