Cursor Agent 2f763e124b fix(ci): set LIBCLANG_PATH on Linux; install Vulkan via brew on macOS ...

Two follow-ups to the previous CI deps commit:

1. Linux: libclang-dev installs libclang.so under
   /usr/lib/llvm-*/lib and /usr/lib/x86_64-linux-gnu, but
   bindgen-0.72.1 does not probe the llvm-versioned directory by
   default. Resolve the newest /usr/lib/llvm-*/lib candidate
   dynamically and export LIBCLANG_PATH so bindgen finds it without
   any clang-sys guesswork. Also install glslang-tools + spirv-tools
   so find_package(Vulkan COMPONENTS glslc) succeeds against
   ggml-vulkan's cmake step.

2. macOS: llama-cpp-sys-2 sets GGML_VULKAN=ON unconditionally when
   the vulkan feature is enabled; cmake's find_package(Vulkan) then
   fails on a vanilla macOS-latest runner because there is no
   Vulkan SDK shipped by default. The LunarG macOS SDK ships as a
   non-scriptable interactive installer, so we compose MoltenVK +
   Vulkan loader + headers + shaderc via Homebrew formulae instead.
   Export VULKAN_SDK=$(brew --prefix) and CMAKE_PREFIX_PATH=same so
   both the build.rs branch and cmake's FindVulkan resolve headers /
   libs / glslc from /opt/homebrew.

Applied symmetrically to check.yml and build.yml. Windows config is
unchanged.
