将 AddButton 移出 role="tablist" 的可访问性所有权。

当 editable 开启且 hasDropdown 为 false 时，Line 622 的 AddButton 仍渲染在这个 role="tablist" 容器内。Line 629 只在有隐藏标签时设置 visibility: hidden，所以正常的可编辑场景仍会把 add control 暴露为 tablist 的后代。这不满足“tablist 只拥有 role="tab" 元素”的要求，并可能继续触发 aria-required-children 检查。

请保留现有布局、tabListRef 尺寸计算和 overflow 行为，但将内层 AddButton 放到 tablist 的同级容器。同时在 tests/index.test.tsx 增加 editable 场景，断言该按钮的 closest('[role="tablist"]') 为 null。
