📄 Description

Fix the issue: https://github.com/games-on-whales/wolf/issues/233#issuecomment-3471903432

I discovered that Wolf retrieves the cuda_device_id by reading the 'Device Minor' number, which appears to be the source of the problem. On my system, cuda_device_id shoud return in ascending order based on PCI addresses.
