test(sim): reproducible green-baseline gate + mark clan_fairness_band non-gating

Adds scripts/green-pass.sh — the hardened-baseline gate: cargo nextest --workspace
+ all sim scenarios through the real resolver, exit 0 only when fully green. It is
gating-aware: a scenario with "gating": false is run and reported but does not fail
the baseline.

Marks clan_fairness_band non-gating (owner decision): it measures SCRIPTED
clan-personality balance (tech_rusher ~46%, 3 personalities at 0% winrate) — a real
imbalance, but the project's answer is TRAINED/learned controllers, not scripted
rebalancing. The 0.4 ceiling is left untuned so the gap stays visible. Fix path:
train learned controllers toward the 6 clan types (docs/ai-roadmap.md).
