Removed temperature defaults from constructor parameters in:
- OpenAI Gpt model (was 1.0)
- LmStudio Completions model (was 0.7)
- Gemini model (was 1.0)
- Bedrock Nova model (was 1.0)
- Anthropic Claude model (was 1.0)

Also removed temperature from example files to let models use their natural defaults.
