Halo-Lipsy is a native Wav2Lip implementation for ComfyUI that finally works on AMD APUs with unified memory (Strix Halo, etc.). Key features: - No subprocess hacks - runs natively in ComfyUI process - Face detection on CPU to prevent memory conflicts - Safe tensor casting for unified memory compatibility - Sync tuning and edge blending options - Works on ROCm, AMD APUs, and NVIDIA Tested on Ryzen AI Max+ 395 (Strix Halo) with 64GB unified memory and ROCm 7.11.

Summary
Adding Halo-Lipsy - a native Wav2Lip lip sync node that finally works on AMD APUs with unified memory.
Why This Node Exists
Existing lip sync nodes fail on AMD unified memory systems because they:
subprocess.run()which escapes the venv → library mismatches → crashvfloat16tensors directly to NumPy → unified memory conflictHalo-Lipsy fixes all of this:
.float().cpu().numpy()Features
