Torch device selection for Moirai-MoE (no uni2ts import — safe for lightweight unit tests).

resolve_moirai_moe_torch_device(device_setting)

Map settings.yaml device string to a torch.device.

• auto / cuda_if_available: CUDA when torch.cuda.is_available else CPU.
• cuda: CUDA only; raises if CUDA is not available.
• cuda:N: specific GPU index when CUDA is available.
• cpu: CPU.

Parameter	Type	Default	Description
