fix: enable real-time streaming regardless of verbose setting

- Remove dependency on verbose=True for streaming display function
- Allow stream=True to work with verbose=False for real-time output
- Maintain backward compatibility with existing verbose=True usage
- Fixes issue where Gemini/Google Vertex AI streaming was buffered

Resolves #956
