The trigger supports click, ArrowDown, and Escape. Root open/close is driven by a real `bootstrap.Dropdown` instance on the trigger (the panel carries Bootstrap's `dropdown-menu`/`show` classes); submenus remain BaseUI's own hover/click behavior. Events: `baseui:open`, `baseui:close` (BaseUI), plus the underlying `show.bs.dropdown`/`shown.bs.dropdown`/`hide.bs.dropdown`/`hidden.bs.dropdown`.
