Summary

This PR adds a runtime validation path for exported workflows so exporter changes can be checked at two levels:

• fast exporter-only validation
• runtime validation against a pinned local ComfyUI checkout

It includes committed fixtures for:

• upscale-model-loader
• text-to-image
• unsafe-kwargs
• subgraph-identifiers

It also updates the exporter so generated scripts preserve workflow metadata and hidden runtime inputs needed for end-to-end execution.

Included

• runtime validation harness in tests/runtime/run_runtime_validation.py
• runtime fixtures in tests/fixtures/runtime/
• exporter support changes in comfyui_to_python.py

Validation

Planned validation commands:

uv run python tests/runtime/run_runtime_validation.py --tier fast --fixture all
uv run python tests/runtime/run_runtime_validation.py --tier runtime --fixture all

Runtime-tier failures are classified as:

• repo regression
• model provisioning failure
• fixture bug
• environment/setup failure
