feat: extend buildStreamTextParams to include capabilities for enhanced AI functionality

- Updated the return type of `buildStreamTextParams` to include `capabilities` for reasoning, web search, and image generation.
- Modified `fetchChatCompletion` to utilize the new capabilities structure, improving middleware configuration based on model capabilities.
