test for all custom nodes #122
Description
the test introduced in d408483 covers a wide range of nodes but not all
Particularly video related node (wan etc.) have not been covered since they would require a different workflow. Not sure if it's feasible to run them on CPU but we could try with GGUFs (to keep memory usage in check), lightning lora, small resolution and just a few frames
We could also auto-generate a smoke test which would instantiate all custom nodes in workflow without actually wiring and executing them
