This ensures that GitHub Actions never reuses outdated Docker layers and that
each test run starts from a fully clean environment. The workflows for
test-container and test-e2e now explicitly invoke:
distro="${{ matrix.distro }}" make build-no-cache
before executing the actual tests.
This aligns the CI behaviour with local testing, eliminates hidden caching
differences, and guarantees deterministic test results across all distros.
