Pull Request Overview

This PR adds support for generating test harnesses for services without streaming methods by introducing conditional generation of WebSocket-related code. The change ensures that non-streaming services don't include unnecessary WebSocket infrastructure in their test harnesses.

• Updates the HTTP harness template to conditionally include WebSocket upgrader and dialer based on whether the service has streaming methods
• Adds test cases to verify correct code generation for both streaming and non-streaming services
• Refactors the stream detection logic to use the IsStreaming() method instead of direct field comparison
