I wrote this PR by hand, without using Opus, and take full resonsibility for its content, and won't blame Opus.

Thanks!

The branch is out of date with main, missing the workflow fix from #428
that pins torch to CUDA 12.8 for CUDA tests. Without this, `pip install
torch` pulls torch 2.11.0 built against CUDA 13, which is incompatible
with the CUDA 12.8 toolkit on the runner, causing all torch+CUDA dlpack
tests to fail.
