Function extract_bindings_with_paths 

pub fn extract_bindings_with_paths(
    value: &Value,
) -> Vec<(String, ExtractedBinding)>

Like extract_bindings but pairs each binding with the dotted arg-field path it sits under (empty for a top-level string, field.sub for nested objects, field.N for array elements). Authoring surfaces use the path to name the consumer input pin a binding wires into.
