fix: stop CLI from overriding LLM-recommended avg_degree and rewire_prob

Changed avg_degree and rewire_prob CLI defaults from hardcoded values
(20.0 and 0.05) to None sentinels. Only include them in base_updates
when explicitly passed via --avg-degree or --rewire-prob, preserving
the LLM-generated or YAML-loaded values.
