📝 Walkthrough

Walkthrough

This PR uniformly downgrades cuDSS dependency constraints from the 0.8.x series to the 0.7.x series across the entire project. The change affects CI installation logic, CMake package discovery, central dependency declarations, conda environment specifications, conda recipe packaging, and Python project metadata.

Changes

cuDSS version pinning update

Layer / File(s)	Summary
Central dependency configuration and wheel/conda pins dependencies.yaml	Central conda and wheel dependency constraints updated from >=0.8,<0.9 to >=0.7,<0.8 for libcudss-dev, nvidia-cudss-cu12, and nvidia-cudss-cu13 across CUDA 12 and CUDA 13 variants.
CI installation and CMake build discovery ci/utils/install_cudss.sh, cpp/cmake/thirdparty/FindCUDSS.cmake	Installation script package globs and version constraints updated to 0.7.*, and CMake find_package minimum version lowered from 0.8 to 0.7 for unpinned CUDSS_DIR discovery path.
Conda environments and recipe packaging conda/environments/all_cuda-129_arch-aarch64.yaml, conda/environments/all_cuda-129_arch-x86_64.yaml, conda/environments/all_cuda-132_arch-aarch64.yaml, conda/environments/all_cuda-132_arch-x86_64.yaml, conda/recipes/libcuopt/recipe.yaml	All four conda environment libcudss-dev constraints updated to >=0.7,<0.8; libcuopt recipe top-level host, per-package host, runtime, and test host requirements updated to the 0.7.x series.
Python project dependency python/libcuopt/pyproject.toml	Python project nvidia-cudss-cu13 dependency updated to >=0.7,<0.8.
