[Bug] Missing ManualCast node – can't load workflow

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

I'm trying to load a workflow that uses the ManualCast node

Is there an alternative way to install ManualCast or a workaround to avoid this error?

### Actual Behavior

### Steps to Reproduce

```powershell
