refresh cbc - update cuda compiler version

[cbouss]

Following https://github.com/anaconda/aggregate-duct-tape/pull/38

• Reorder global section (move compiler versions next to the corresponding compilers)
• Update cuda compiler version from 12.4 to 12.9 and 13.1 13.0
• Remove BUILD workaround (addressed in conda-build 25.11.0 linux_vars function setting BUILD wrong when cdt_name is in use conda/conda-build#5733)
• Remove inactive projects from pins, or projects that are pinning exceptions: https://github.com/anaconda/aggregate-duct-tape/blob/main/scripts/update_aggregate_conda_build_config.py#L120
• Remove cuda related package pins (example: cuda_cudart). These packages depend on cuda-version, which effectively handles which versions to pull depending on the cuda compiler used.

LGTM. Thanks!

Unpopular (but safer) option: What about using 13.0 instead of 13.1? The reason is simple: CUDA minor version compatibility.

I agree some libraries have to depend on 13.1, e.g. with CUDA Tile dependencies, and some of them, like cuda-bindings require specifying the exact CUDA version. Apart from these, for 13.x, majority of the libraries support the minor version compatibility (or advanced enhanced compatibility).

Use of 13.1 (or later) could be reconsidered in a couple of months, depending on the changes in CTK.

After some research, I agree with you.

The GPU feature list did not change between 13.0 and 13.1:
https://docs.nvidia.com/cuda/archive/13.0.0/cuda-compiler-driver-nvcc/index.html#gpu-feature-list
https://docs.nvidia.com/cuda/archive/13.1.0/cuda-compiler-driver-nvcc/index.html#gpu-feature-list

13.1 requires a slightly higher driver than 13.0.

This doc: https://github.com/AnacondaRecipes/cuda-feedstock/blob/main/recipe/doc/recipe_guide.md#cuda-enhanced-compatibility indicates we could build with 13.1 while keeping maximum range (provided we take the appropriate steps). However, identifying appropriate steps seems error prone.

There is also cuda-compat, but that is linux only.

Considering all this, setting the default to 13.0 does seem to be the right call.

@ELundby45 @xkong-anaconda you're good with 13.0 instead of 13.1?

That documentation is a hidden gem :)

I'm good with that. Thanks for flagging and investigating.

+1 on 13.0

LGTM! Thank you very much @cbouss, @ELundby45 and @xkong-anaconda !
