Cap quality here and save

Hard questions go to this model, easy ones drop to something cheaper. Set a savings target (0–0.8) and the router tunes itself until realized savings converge on it.

{
  "model": "celon/auto",
  "celon": {
    "anchor": "nvidia/nvidia-nemotron-3-ultra-550b-a55b-bf16",
    "savings_target": 0.4
  }
}

Naming a model directly gets you that model — savings controls don't apply.
