ci: switch gadfly review to the reusable workflow (curated swarm, 5 lenses)

Replace majordomo's full self-contained Gadfly stub with a thin caller of
steve/gadfly's reusable workflow, matching mort/executus's hardened pattern:
- explicit secret forwarding (least privilege); GITEA_TOKEN is the auto token.
- pinned to an immutable gadfly commit (@20a5c43), not @main.

Curated swarm tuned for majordomo:
- 3 strong cloud models (minimax-m3, glm-5.2, deepseek-v4-pro) — dropped
  qwen3-coder:480b, nemotron-3-super, glm-5.1.
- Claude Code engine (sonnet, opus, opus:max), claude-code=3 so all three
  claudes run at once.
- 5-lens default suite (security, correctness, maintainability, performance,
  error-handling) for every model (lenses are global).
