Community ONNX Passes

Community-contributed ONNX passes operate on ONNX graph models (onnx.ModelProto) and use the onnx_ pass-name prefix, exactly like core ONNX passes. For the implementation contract, naming conventions, and worked examples, see ONNX Model Passes and Adding New Passes.

No community ONNX passes are currently shipped. When you contribute one, document it here with its pass name, configuration parameters, and behavior, matching the style of the core ONNX pass reference.
