mohdel v3.16.2

Fixed

• A Gemini 4 call with an effort sends thinkingLevel, as on Gemini 3; it
  sent a numeric thinkingBudget and raised maxOutputTokens by it.

Changed

• A ChatGPT call with an outputBudget is refused as INVALID_REQUEST; the
  route documents max_output_tokens as a field to omit.
