fix: address code review feedback for GPT-5 implementation

- Replace console.warn with conditional debug logging using DEBUG_RESPONSES_API flag
- Rename prepareResponsesApiInput to prepareStructuredInput for clarity
- Improve type safety in Task.ts by removing any type casting
- Use GPT5_MODEL_PREFIX constant consistently
- Update tests to use renamed method
