HumanoidMocap/Core/Solve/TargetRigMappingExtensions.cs
Extension method for TargetRig that converts its bone role annotations into a MappingResult structure so target-side code can reuse source mapping logic. It constructs a MappingResult, sets Confidence, and maps annotated BoneRole values to bone indices.
