Some OpenRouter reasoning models (e.g. nvidia/nemotron-3-super-120b-a12b:free)
emit chain-of-thought into message.content, so even strict prompts like
"Reply with exactly: PONG" produce visible reasoning preamble. Add a default
model_list entry that sets extra_body.reasoning.exclude=true so OpenRouter
strips reasoning server-side, plus a config test and docs note covering the
symptom, cause, and per-model tradeoff. No global auto-injection: reasoning
visibility stays a per-model choice.
