import { ReorderCommitHandler } from '@cngx/forms/select'

dispatch#void

dispatch(next: T[], previous: T[], fromIndex: number, toIndex: number, option: CngxSelectOptionDef<T> | null)

Run a reorder through the commit flow.

No commit: write values, fire onReorder + onAnnounce.
Optimistic: write, emit, begin commit. Success reconciles with the server's canonicalised value; error rolls back.
Pessimistic: hold values, emit 'pending', begin commit. Success writes + emits; error leaves values untouched.

Always writes on success regardless of same-membership - the point of this factory is to bypass sameArrayContents.
