Vulkan Inference (Intel Arc)

Demonstrate wgpu/Vulkan inference on non-NVIDIA hardware (Intel Arc iGPU). Detects GPU backend via platform probing, benchmarks CPU vs simulated Vulkan matmul, and identifies the crossover point where GPU beats CPU.

Device:

cargo run --example gpu_vulkan_inference

Key concepts: wgpu backend detection, Intel Arc device probing, Vulkan pipeline configuration, CPU/GPU crossover analysis.
