Add reasoning/thinking configuration handling for Claude and OpenAI translators

Browse Source 
- Implemented `thinkingConfig` handling to allow reasoning effort configuration in request generation.
- Added support for reasoning content deltas (`thinking_delta`) in response processing.
- Enhanced reasoning-related token budget mappings for various reasoning levels.
- Improved response handling logic to ensure proper reasoning content inclusion.
