📝 Walkthrough

Walkthrough

This PR reorganizes ComfyUI node schema metadata across many files without changing runtime behavior. It adds or updates node display_name fields, normalizes and reclassifies category strings (e.g., detection, experimental, image/transform, video/preprocessors, advanced/model_merging), removes two UI inputs from WanContextWindowsManualNode schemas, and adds a NODE_DISPLAY_NAME_MAPPINGS entry for unCLIPCheckpointLoader. No execution logic, public signatures, or data contracts were altered.

95-95: ⚡ Quick win

Remove the stale inline comment.

The comment # "sampling/custom_sampling/samplers" left on the category line is ambiguous — it reads like commented-out code hinting at a future promotion path, but it's unclear intent and adds noise. If the graduation path needs to be tracked, a TODO comment or an issue is clearer.

🧹 Suggested cleanup

-            category="experimental",  # "sampling/custom_sampling/samplers"
+            category="experimental",
