On Windows VMs with para-virtualized GPUs, QMD may use Vulkan offloading instead of pure CUDA mode even when CUDA is available. This adds QMD_FORCE_CUDA env var to force CUDA and disable Vulkan: export QMD_FORCE_CUDA=1 qmd query "test" Fixes tobi#278

Problem
On Windows VMs with para-virtualized GPUs (e.g., ExHyperV RTX 4090), QMD may use Vulkan offloading instead of pure CUDA mode even when CUDA is working correctly:
Solution
Add
QMD_FORCE_CUDAenvironment variable to force CUDA and disable Vulkan:This sets
gpu: "cuda"ingetLlama()options, bypassing the auto-detection that might choose Vulkan.Related
