feat: add model-to-node backlinks for upcoming custom nodes (#9411)

## Summary
- Add `quickRegister()` mappings for models being added in open cloud
PRs so the "Use" button works when those node packs ship

## Mappings added

| Cloud PR | Node Pack | Model Directories | Loader Node |
|----------|-----------|-------------------|-------------|
| [#2645](https://github.com/Comfy-Org/cloud/pull/2645) |
ComfyUI-HunyuanVideoWrapper | `LLM/llava-llama-3-8b-*` |
`DownloadAndLoadHyVideoTextEncoder` |
| [#2598](https://github.com/Comfy-Org/cloud/pull/2598) |
comfyui-cogvideoxwrapper | `CogVideo/GGUF`, `CogVideo/ControlNet` |
`DownloadAndLoadCogVideoGGUFModel`, `DownloadAndLoadCogVideoControlNet`
|
| [#2594](https://github.com/Comfy-Org/cloud/pull/2594) |
ComfyUI-DynamiCrafterWrapper | `checkpoints/dynamicrafter{,/controlnet}`
| `DownloadAndLoadDynamiCrafterModel`,
`DownloadAndLoadDynamiCrafterCNModel` |
| [#2537](https://github.com/Comfy-Org/cloud/pull/2537) |
ComfyUI_LayerStyle_Advance | `BEN`, `BiRefNet/pth`, `onnx/human-parts`,
`lama` | `LS_LoadBenModel`, `LS_LoadBiRefNetModel`,
`LS_HumanPartsUltra`, `LaMa` |

## Safe to merge before backend

Unknown node classes are silently skipped by `registerNodeProvider()` —
the mapping becomes a no-op until the node pack is deployed. Zero risk.

## Test plan
- [ ] Verify no runtime errors on load (unknown classes are skipped
gracefully)
- [ ] After backend PRs merge, verify "Use" button creates correct node
for each model type
