CngxMenuSeparator

Visual + semantic separator inside a CngxMenu. Renders role="separator" with aria-orientation="horizontal". Does not register CNGX_AD_ITEM, so the surrounding CngxActiveDescendant skips it during arrow-key navigation and typeahead - required for action-menu and dropdown-menu patterns where separators visually group items but are not selectable.
