feat(aiCore): update ai-sdk-provider and enhance message conversion logic

- Upgraded `@openrouter/ai-sdk-provider` to version ^1.1.2 in package.json and yarn.lock for improved functionality.
- Enhanced `convertMessageToSdkParam` and related functions to support additional model parameters, improving message conversion for various AI models.
- Integrated logging for error handling in file processing functions to aid in debugging and user feedback.
- Added support for native PDF input handling based on model capabilities, enhancing file processing features.
