Add QuantizedLoRALoader and QuantizedLoraStack nodes that use bypass mode to properly handle QuantizedTensor wrappers and all quantization formats. Supports stacking multiple LoRAs with individual strength controls and on/off toggles.

Key features:

  • QuantizedLoRALoader: Load single LoRA with bypass mode
  • QuantizedLoraStack: Stack up to 8 LoRAs with on/off toggles
  • Uses comfy.sd.load_bypass_lora_for_models() for quantized compatibility
  • Supports all quantization formats (INT8, FP8, MXFP8, NVFP4, BNB 4-bit)
  • Bypass mode injects LoRA computation during forward pass

There is already bypass mode LoRA loaders in ComfyUI core though.

Try to stack 2 loras using the bypass
