- Add unique_id and extra_pnginfo parameters for workflow persistence
- Implement Show Text-style workflow updating to preserve JSON data across reloads
- Add OUTPUT_NODE = True to enable standalone execution without downstream nodes
- Fix onConfigure to skip pretty_format widget value and only display JSON data
- Resolve "true" string display issue on page reload
Now PoseKeypointPreview works like Show Text:
- Displays without requiring downstream nodes
- Preserves JSON content across browser reloads
- Properly handles widget state management
