Address review: renamed repo watch, full checkdepends, llvm rebuild

- watch joshuaswarren/omarchy-mlx (the url= repo) instead of mlx-omarchy
- global checkdepends gains 'lapack' 'blas' 'vulkan-icd-loader' alongside
  'openblas', the shared libraries the wheel loads at check() import
- rebuild_on llvm: omarchy-mlx-vulkan links the shared libLLVM
