- Create WidgetValue union type for all valid widget values
- Replace 'any' types with proper generic constraints in SimplifiedWidget
- Add runtime validation for widget values in useGraphNodeManager
- Update WidgetSelect to use constrained generics instead of any
- Fix type assertions with proper validation functions
- Ensure SafeWidgetData uses WidgetValue type consistently
This eliminates most 'any' usage while maintaining runtime safety through validation.
- Widget callbacks now explicitly set widget.value (fixes empty LiteGraph callbacks)
- Created useWidgetValue composable for consistent widget patterns
- Updated all widget components to use proper props/emit pattern
- Callbacks are set up before data extraction to ensure proper state sync
