[WIP] Add tests for logic errors in endend.py

[Copilot]

Plan to add tests for logic errors in endend.py:

• Create test file structure (test_endend.py)
• Add tests for sanitize_model_name function (input validation, special characters)
• Add tests for normalize_model_name_for_matching function (pattern generation)
• Add tests for fuzzy_match_score function (scoring logic)
• Add tests for validate_virtual_environment function (path validation)
• Add tests for detect_openvino_model_type function (model type detection)
• Add tests for parse_log_file function (log parsing logic)
• Add tests for helper functions (search_metric, get_quantization_patterns)
• Run tests to ensure they pass
• Document test coverage
