(Listbox, Select, Combobox, Menu). It provides value-based keyboard
navigation, selection/activation modes, typeahead, and aria-activedescendant
virtual focus.
Listbox: standalone selectable list with single/multiple selection.
Select: floating dropdown with trigger, keyboard navigation, form integration.
Also fixes exactOptionalPropertyTypes compatibility in createDisclosureState
and createListNavigation interfaces.
Reactive wrapper around @floating-ui/dom that auto-updates floating
element position relative to an anchor. Exports createFloating,
CreateFloatingOptions, and FloatingState from primitives index.
Implements the controlled/uncontrolled state primitive with full TDD coverage (5 tests passing). Delegates to an internal signal when uncontrolled, defers to the external value accessor when controlled.
