Feature Description

U need this fix to run on vulkan 12a345f1518643dc471f9cbf84528313e6aea07b

git fetch origin pull/88/head:pr-88
git checkout pr-88
git submodule update --init --recursive

I used this to compile with vulkan and it worked after a small fix in the code

ran the command without turbo just to test if it runs anything:
llama-cli -m
Qwen_Qwen3.6-35B-A3B-IQ4_XS.gguf
--spec-type dflash --spec-draft-model
qwen36-35b-a3b-dflash-IQ4_XS.gguf
--spec-draft-ngl all --flash-attn on

place this build.bat outside beellama.cpp, it will auto detect
visual studio https://visualstudio.microsoft.com/downloads/
and
vulkan sdk https://vulkan.lunarg.com/sdk/home#windows
