    Class ArrayTreeDatasource<T>

    Simple in-memory tree datasource backed by an array of root nodes.

    The constructor takes a defensive copy of the root array so that external mutations do not affect the tree. Child nodes are read from a configurable property on each TreeNode, defaulting to 'children'.

    // Default — reads children from `node.children`
    const ds = new ArrayTreeDatasource([
      { id: '1', data: 'Root', children: [
        { id: '1.1', data: 'Child' },
      ]},
    ]);

    // Custom property — reads children from `node.items`
    const ds2 = new ArrayTreeDatasource(roots, 'items');
