Subgraphs don't reliably mute or bypass, they still run if the group they are in is set to never.

### 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

That the subgraph will mute or bypass

### Actual Behavior

Subgraph still runs

### Steps to Reproduce

Run attached WF, mute of bypass Process group

### Debug Logs

```powershell
Nothing in log
```

### Other

[BasicStyleFluxv3.json](https://github.com/user-attachments/files/23480562/BasicStyleFluxv3.json)

Start by importing the attached BasicStyleFluxv3.json workflow and reproducing the Process group with mute and bypass enabled. Trace the frontend's subgraph and group execution-state handling to determine why the subgraph still runs, then verify that both modes prevent execution without introducing log errors.
