 *
 * Takes an array of TreeItem objects and renders them as an expandable tree.
 * Provides context for selection and expand/collapse state.
 *
 * @fires tree-select - When an item is selected. Detail: { id: string, item: TreeItem }
 *
 * @example
 * ```html
 * <ef-tree
 *   .items=${[
 *     { id: "folder1", label: "Folder 1", children: [
 *       { id: "file1", label: "File 1" },
 *       { id: "file2", label: "File 2" },
 *     ]},
 *     { id: "file3", label: "File 3" },
 *   ]}
 *   @tree-select=${(e) => console.log('Selected:', e.detail.id)}
 * ></ef-tree>
