ZhouXuan-Yu/dsh-model-rotation

Model rotation for DeepSeek Harness: groups each provider's models by source, orders them by hand or by measured success rate and latency, stores model plus reasoning-effort presets, falls over to the next entry when a model hits its quota or is unavailable, resends the same step on the next model, and shows which model actually answered. Uses the models of whatever provider plugins are already installed (Antigravity accounts, Codex subscription, DeepSeek API keys); it does not provide model access itself.
