Replace majordomo's full self-contained Gadfly stub with a thin caller of
steve/gadfly's reusable workflow, matching mort/executus:
- explicit secret forwarding (least privilege) instead of broad exposure;
GITEA_TOKEN is the automatic job token.
- pinned to an immutable gadfly commit (@20a5c43), not @main.
- adds the Claude Code engine (sonnet, opus, opus:max) to the 6 cloud models.
- provider_concurrency claude-code=3 so all three claudes run at once.
