#79 renamed the config to renovate.json5 and left configurationFile pointing at the old
name. Runs 315-322 (2026-10-22..29) all failed in ~1s before Renovate started.
Also add a ci/lint.sh assertion that every workflow configurationFile: resolves to a real
path — valid YAML, so yamllint could not catch it, and the gate stayed green throughout.
