fix: Updated default reasoning model for nvidia (#568)

* Updated default reasoning model for nvidia

* Updated inference params for super

* Add reasoning_effort to Nemotron Super params, update stale docs

- Add extra_body.reasoning_effort=medium to
  NEMOTRON_3_SUPER_120B_A12B_INFERENCE_PARAMS (mirrors GPT-5 config)
- Update README telemetry example and model-configs.md to use
  nvidia/nemotron-3-super-120b-a12b instead of openai/gpt-oss-20b
- Broaden inference-parameters.md reasoning effort tip to cover
  Nemotron Super

* Remove build-time README accidentally tracked
