ci-diagnosis

Diagnose GitHub Actions workflow failures — build errors, skopeo push failures, crane manifest issues, workspace build problems. Use when: A CI workflow run failed, images aren't updating after a push, or someone asks "why did the build fail?" Covers both build-openclaw.yaml and build-workspace.yaml pipelines. Don't use when: The pod is crashing after a successful CI run (use pod-troubleshooting). Don't use for Flux reconciliation issues (use flux-debugging). Don't use for registry inspection when CI succeeded (use zot-registry). Don't use for code-level bugs (use debug-troubleshooting). Outputs: Root cause of CI failure with specific step, error message, and fix recommendation.
