## Title

    [coremltools] torch.export: "Conversion for models with only ATEN or EDGE dialect is supported/tested ... Run '.run_decompositions({})'"

## Body

    Cause (Documented platform behavior): Converter supports ATEN/EDGE dialects only.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - Run '.run_decompositions({})' on your exported PyTorch Model prior to conversion.
