[Cloud] Request: Add kentskooking-nodes to cloud.comfy.org supported custom nodes

## Custom node pack to add

**Repo** : https://github.com/Kentskooking/kentskooking-nodes
**License** : GPL-3.0
**Status** : Mature, in active community use

## What it does

kentskooking-nodes is a **wave-driven iteration framework** with 14 custom nodes that enables:
- Frame-by-frame progressive refinement (`ImageIterativeSampler`, `VideoIterativeSampler`)
- Morphing between two video sources (`VideoInterpolateSampler` + `InterpolationWaveController`)
- Conditioning space exploration between two prompts (`ExplorerConditioningSampler`)
- Wave-modulated parameters: zoom, denoise, clip_strength, IPAdapter weight, ControlNet strength
- Resume from checkpoint for long renders (`IterativeCheckpointController`)
- WaveVisualizer for debugging wave parameters

## Why it should be on cloud

- 14 nodes, all serving a coherent and well-tested pipeline
- Compatible with FLUX, SDXL, SD 1.5, Z-Image (tested in their own examples folder)
- The wave-driven iteration produces unique visual effects (cycle-based morphing, progressive zoom-in, time-shift exploration) not achievable with standard samplers
- Use cases: experimental video art, music videos, motion design, AI-generated film sequences

## Tested setup that requires this on cloud

I've fully validated kentskooking-nodes locally with Z-Image-Turbo (8 working workflows, see [repo](https://github.com/12georgiadis/kentskooking-zimage-demo)). The pipeline works great. But on cloud.comfy.org:

```
POST /api/prompt
{"error":{"message":"Invalid workflow: unsupported node type 'ImageWaveController'","type":"VALIDATION_ERROR"}}
```

I'd love to run these workflows on Comfy Cloud (paid Creator subscription) to scale to higher resolution / longer batches that don't fit on my local RTX 5090.

## Request

Add kentskooking-nodes to the cloud whitelist (https://comfy.org/cloud/supported-nodes/). Happy to provide example workflows and stress-test if useful.

Thanks!
