+Improve Floating UI usage: fix `arialLabel` typo in `MenuTrigger`, replace imperative floating ref in `MenuList` with `useMergeRefs`, remove manual position offset in `SelectOptionList`, add `aria-haspopup` to `MenuTrigger`, and add missing ARIA attributes (`aria-expanded`, `aria-haspopup`, `role`, `aria-selected`) to `Select` components.
