New:

• Vulkan GPU inference (llama-vulkan)
• Auto GPU detection; automatic CPU fallback

Usage:

• Auto: --engine auto
• GPU: --engine llama-vulkan
• CPU: --engine llama-cpu

Linux setup:

• Loader/tools: libvulkan1 vulkan-tools
• Drivers: nvidia-vulkan-icd or mesa-vulkan-drivers

Validate:

• ldconfig -p | grep libvulkan.so.1
• vulkaninfo | head

Notes:

• CPU-only environments continue to work
• If Vulkan missing and GPU forced, startup may fail or warn, per config
