Pull request overview

This PR adds unit test coverage to ensure OnnxDiscrepancyCheck’s generation-comparison path correctly auto-detects ORT GenAI exporter artifacts produced by MobiusBuilder (via presence of genai_config.json) and behaves consistently with the existing ModelBuilder-based flow.

Changes:

• Add tests verifying a Mobius export directory containing genai_config.json is used as genai_model_path for generation metrics.
• Add a test ensuring the first_token_20 metric forces max_new_tokens=20 when running generation comparison.
• Add a test ensuring generation comparison is skipped when a Mobius export directory lacks genai_config.json.
