zeekay 18e6cee0ae feat: Vulkan (SPIR-V) compute backend plugin for lux-accel
Core Vulkan 1.1 compute implementing backend_api.h. SPIR-V kernels via
create_kernel_from_bundle; GLSL->SPIR-V at runtime via libshaderc for
create_kernel_from_source. Runs live on macOS through MoltenVK; native ICDs on
Linux. Verified: Apple M1 Max vector-add, bit-identical to CPU reference.

# The plugin only needs backend_api.h from lux-accel at build time. It is
# a host requires (not tool_requires) so CMakeDeps emits lux-accel's
# include dirs — a build-context tool dep has its usage requirements
# stripped, leaving <lux/accel/backend_api.h> unresolvable. lux-vulkan
# never links lux-accel (it is a dlopen'd plugin, libs=[]). The Vulkan
# loader/headers and (optional) libshaderc are located via CMake; if the
# loader is absent the plugin builds as a stub reporting is_available()==0.
