Local video generation on Android: ~550-600s per clip on Snapdragon 8 Gen 3

A developer continues local image/video generation experiments on Android: on a OnePlus 12 (Snapdragon 8 Gen 3), he generated a text-to-video clip ('black cat playing guitar in a forest') at 512x320, 49 frames @24fps, in 550-600s using Neodragon int8 / Z Image Turbo int4 across CPU and GPU, with the start frame rendered via OpenCL. He avoids sd.cpp due to slow Android GPU inference and OOM crashes, and prioritizes broad device compatibility over NPU-specific speedups.
