feat: db list and image support

[damzobridge]

This PR adds reactive hooks for fetching List and Image property types.

New Hooks

useViewModelInstanceImage

• Returns: { setValue } - setter function to update images

useViewModelInstanceList

• Returns: Object with list manipulation functions:
  • length - Current list length
  • addInstance(instance) - Add item to end
  • addInstanceAt(instance, index) - Insert item at specific index
  • removeInstance(instance) - Remove by instance reference
  • removeInstanceAt(index) - Remove by index
  • getInstanceAt(index) - Get item at index
  • swap(indexA, indexB) - Swap two items

Usage Examples

Image Property:

const { setValue: setImage } = useViewModelInstanceImage('profileImage', viewModelInstance);

// Load and set image
const imageBuffer = await fetch(imageUrl).then(r => r.arrayBuffer());
const decodedImage = await decodeImage(new Uint8Array(imageBuffer));
setImage(decodedImage);
decodedImage.unref(); // Clean up

List Property:

const { length, addInstance, getInstanceAt, removeInstanceAt } = 
  useViewModelInstanceList('todoItems', viewModelInstance);

// Add new todo item
const todoViewModel = rive?.viewModelByName?.('TodoItem');
const newItem = todoViewModel.instance();
addInstance(newItem);

// Remove first item
removeInstanceAt(0);
