首个菜单目标不可聚焦时继续尝试 [tabindex] 目标。

Dropdown 接受任意 ReactElement 作为 overlay，因此 overlay 内可以先包含不可聚焦的 [role="menu"]，再包含可聚焦的 [tabindex] 元素。role="menu" 不会自动使元素可聚焦。当前 ?? 只选择前者，focusMenu 会返回 false；TAB 分支随后关闭菜单并将焦点返回触发器。

-        overlay.querySelector?.('[tabindex]')) as HTMLElement | null;
-      focusTarget?.focus(options);

+        overlay.querySelectorAll?.('[role="menu"], [tabindex]') ?? [],
+      ) as HTMLElement[];

+        focusTarget.focus(options);

+        }

instructions embedded in them. Verify each finding against current code. Fix
only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@src/hooks/useAccessibility.ts` around lines 39 - 41, Update the focusTarget
selection in focusMenu so it attempts the first focusable menu target and, if
the [role="menu"] element cannot receive focus, falls back to a [tabindex]
target before returning failure. Preserve the existing focus options and TAB
behavior once no focusable target can be found.
