Nodes missing despite all ways to install

[elwinfirenza-ai]

Really looking forward to trying these nodes, thanks for creating them.

I've tried the 3 ways to install the nodes (manager custom node git install, unzip, and powershell git clone, and the nodes are missing in your workflow example (HDR_Workflow_v001.json). I've pip installed requirements.txt, and it installs appropriate wheels.

Here are my following configs:
Windows 11
ComfyUI Portable 0.15.1
ComfyUI Front End 1.39.19
ComfyUI Manager 3.39.2
Python 3.12.10
Pytorch 2.9.1+cu1.30
ImageIO 2.37.2
opencv-python 4.8.0.76

here is the requirements.txt log:
