v3.0.3 — pyinfra-smoke heredoc fix Single-fix patch release. Carmine pipeline failed to lint at v3.0.2 because pyinfra-smoke's heredoc-in-script form lints clean inside the catalog (which doesn't self-test pyinfra-smoke) but breaks downstream consumer lint. Replace storage.conf heredoc with single printf line. Self-test gap noted in CHANGELOG: v3.1 should extend consumer-test to exercise pyinfra-smoke, image-verify, bootc-boot-smoke against realistic targets so the catalog catches these in isolation.
