Module gpu_detector 

GPU inventory detection

Platform-specific GPU detection:

• Linux: Scans /sys/bus/pci/devices for display controllers (VGA and 3D controllers). Identifies vendor (NVIDIA, AMD, Intel) by PCI vendor ID, reads VRAM from PCI BAR regions, and optionally uses nvidia-smi for NVIDIA-specific model and memory information.
• macOS: Uses system_profiler SPDisplaysDataType -json to detect Apple Silicon GPUs and unified memory via sysctl -n hw.memsize.
• Other: Returns an empty GPU list.

No external dependencies required – pure sysfs/system_profiler scanning with optional subprocess calls for enrichment.
