- Add `inlineSearch` prop: renders search input inside the trigger
  instead of the dropdown. Selected items show as badges (multi) or
  as the input value (single). Mutually exclusive with `combobox`.
- Wire floating-ui combobox pattern: input is the interactive
  reference, wrapper div is the position reference. `virtual: true`
  in useListNavigation so items use aria-activedescendant without
  stealing DOM focus.
- UX polish: selected label shown in input on open (no highlight),
  typing appends and filters, search clears on any close (Escape,
  outside-click, or selection), Backspace removes last badge in
  multi mode.
- Add InlineSearchSingle, InlineSearchMulti, InlineSearchWithCombobox
  stories with interaction test coverage.
- Update readme.md and select-types.ts for new prop.
