 * Internal base class for `mdc-list` — the container that owns roving tabindex
 * and keyboard navigation across its `mdc-list-item` children.
 *
 * Items are self-managing views: each item renders its own native root and
 * reports activation through the composed `request-activation` event. The list
 * keeps exactly one interactive item in the tab order (roving tabindex),
 * navigates with Arrow keys / Home / End, and exposes
 * `activateNextItem()` / `activatePreviousItem()` for external callers.
