v1.21.0

Added

• SearchableSelect accepts clearable (plus clear-label for the ✕'s
  accessible name, default "Clear selection"). While something is selected, an
  ✕ appears between the label and the chevron; pressing it emits
  update:modelValue with '' and hands focus back to the trigger.

  Without it the control is a trap for OPTIONAL values: it picks from a closed
  set and only ever emits option.value, so once anything is picked there is
  no gesture that returns to "nothing chosen". The consuming app hit this on
  its data-source form — the store-dialog field is nullable all the way down
  ('nullable' in the FormRequest, ?? null on submit), but a user who
  selected a dialog could never unselect it short of reloading the page. Its
  sibling controls both already had an exit: the native Select renders a
  selectable placeholder <option value="">, and Combobox is free text that
  can be erased. This closes the gap for the third sibling; required fields
  simply don't pass the prop.

  Two deliberate choices, so call sites don't pay for what they don't use:

  • Clearing emits '', not null — the same "nothing chosen" payload
    the native Select produces when its placeholder is picked. Emitting
    null would widen the payload type to T | null for every consumer,
    forcing null-handling onto the majority of call sites whose select is not
    clearable and can never receive it. (For a T = string site, T | ''
    collapses to string: existing handlers type-check unchanged.)
  • The ✕ is a sibling of the trigger, not a child — the trigger is
    itself a <button>, and a button inside a button is invalid HTML that
    browsers "repair" by splitting the elements apart. It is absolutely
    positioned into the trigger's right end at the control's full height, and
    only rendered while a selected option's label is actually on screen (a
    modelValue whose options have not arrived yet shows the placeholder, and
    there is nothing visible to clear).

  The Clearable story pins the loop: clear → model '', placeholder back,
  menu closed, focus on the trigger, ✕ gone; re-pick → ✕ back.
