- Encode prompts under no_grad so cached embeddings hold no autograd graph
that would keep the released text encoder alive.
- Release and reload the pipeline when a prompt stage fails after the DiT
was dropped, instead of failing every later request on transformer None.
- Hash the bundle's pipeline_moss_image.py that the MPS path executes, and
record mps_runtime.py separately, instead of hashing only the wrapper.
