Colorful 2F4C:1018: reconstructing a motherboard ARGB HID interface

Colorful 2F4C:1018 reconstructs the HID commands used to drive a COLORFIRE motherboard's ARGB headers from vendor-app analysis and live probing. It identifies interface 2 as the lighting channel and documents 20-LED data reports followed by commit reports. Included OpenRGB controller code sends direct frames and host-rendered effects.
