Change a temperature parameter for gpt-5

[JakubMajcher]

Hello. I wanted to start using gpt-5-mini or nano, but after exporting WHIZ_LLM_MODEL=gpt-5-nano I have an error:

✖ whiz is thinking...
BadRequestError: 400 Unsupported value: 'temperature' does not support 0 with this model. Only the default (1) value is supported.

    param: 'temperature',
    code: 'unsupported_value'
  },
  code: 'unsupported_value',
  param: 'temperature',
  type: 'invalid_request_error'
}

I see no updates for 2 years in the code. Is the project still alive? I could prepare the PR, but I am not a TypeScript dev and I am not sure is it only change in completion.ts temperature: 1,. Please let me know if someone can do the fix, thanks!
