feat(react-tag-picker): export useTagPickerContextValues and TagPickerControlInternalSlots

Expose the existing context-values hook and the control's internal slots type so
the headless TagPicker (and other consumers) can reuse them instead of
duplicating the logic/type. No rename — exported as-is.
