…em (#149) The forward path builds a DeviceInfo on every call (LayerConfig.check_device, _resolve_use_pdl). Even after #148, fullgraph compile fails there because Dynamo cannot trace the extension's _DeviceInfo constructor. Return one shared instance per device from __new__, so traced code only reads an existing object, and add __reduce__ so copy/deepcopy/pickle resolve to the same device's instance instead of overwriting the current device's. Extend test_forward_fullgraph with int8 activations, which trace may_process_input and check_device.
