Rename Checkpoint-Formats page to Packing-Formats; add Complementary configs nav group - Checkpoint-Formats-and-Compatibility -> Packing-Formats-and-Compatibility (page file renamed; every inbound link retargeted and retitled). - Sidebar + Home: move Rotations/Smoothing/Norm Tuning and EoRA out of Quantization methods into a new Complementary configs group, with deep links to MSEConfig (mse=) and SmootherConfig in QuantizeConfig-Reference. These configs attach to multiple lifecycles rather than being methods.
