OBSBOT Tiny 3: USB control protocol investigation

obsbot-tiny3-protocol investigates direct USB control of the OBSBOT Tiny 3 camera. It documents UVC extension-unit addressing, V3 frame fields and CRC, Tiny 3 AI mode values, and command behavior checked against camera-reported state; Python probes inspect UVC properties and test vendor opcodes.
