OutputGallery nodes were not being handled in externalizeWorkflowImages(),
causing their images arrays (which can contain dozens of high-res base64
images) to remain embedded in workflow JSON even when "Embed images as
base64" was disabled.
This caused workflow files to balloon to 500MB+ and hit JavaScript's
"Invalid string length" limit when saving.
Changes:
- Add outputGallery case to externalizeNodeImages() to clear images array
- Add outputGallery case to hydrateNodeImages() for consistency
- Add cleanup-workflow.js script for fixing existing affected workflows
OutputGallery content is display-only and regenerated on workflow execution,
so it doesn't need to be persisted.
