Merge master into feature/qwen-image-edit-node

Browse Source 
Resolved conflict in comfy_extras/nodes_qwen.py by keeping the alpha channel fix:
- Retained the fix: images_vl.append(s.movedim(1, -1)[:, :, :, :3])
- This ensures only RGB channels are used for vision processing
- Fixes RuntimeError when processing images with alpha channels
