Fix V100 CUDA compatibility for demeter4 runners

ChrisRackauckas · ChrisRackauckas · commit 99782809f280 · 2026-03-19T08:47:35.000-04:00
Add LocalPreferences.toml to pin CUDA runtime 12.6 and disable forward-compat driver. V100 GPUs (compute capability 7.0) require system driver since CUDA_Driver_jll v13+ drops cc7.0 support. Ref: ChrisRackauckas/InternalJunk#19
