oa::ml::save_checkpoint

Save a module and its complete optimizer state in the native OA .oam format. Registration-derived parameter paths become the Weights index. Persistent module buffers become the State index; non-persistent buffers are excluded. This is an explicit host-observation boundary. The completed file is durably written to a sibling temporary path and atomically renamed. Errors Returns an error for ambiguous module ownership, optimizer/model mismatch, unsupported Matrix metadata, readback failure, arithmetic overflow, or a filesystem failure.
