@dunky.dev/vue-dialog	minor

New substrate: the Vue 3 binding for @dunky.dev/dialog. The same compound anatomy and behavior contract as the React binding — one core machine, a new host — delivered in Vue's native shape: the core options are props, the core callbacks are emits, and v-model:open is the controlled contract (update:open reports real transitions only; per the controlled contract a dismissal on a controlled dialog emits nothing — decide it at its source in the dismissal emits, which carry preventDefault() for the veto).

<script setup lang="ts">
import { Dialog } from '@dunky.dev/vue-dialog'
</script>

<template>
  <Dialog v-model:open="open" @escape-key-down="onEscape">
    <Dialog.Trigger>Open</Dialog.Trigger>
    <Dialog.Portal>
      <Dialog.Backdrop />
      <Dialog.Viewport>
        <Dialog.Content>
          <Dialog.Title>Title</Dialog.Title>
          <Dialog.Description>Description</Dialog.Description>
          <Dialog.Close>Close</Dialog.Close>
        </Dialog.Content>
      </Dialog.Viewport>
    </Dialog.Portal>
  </Dialog>
</template>

Content's initialFocus accepts a MaybeRefOrGetter<HTMLElement | null> — the Vue idiom for "resolve at open time", so template refs that fill after setup work. Everything else follows the core spec: native <dialog> window, layer stack with assistive-tech containment, focus trap with Close as the cycle's last stop, scroll lock (scoped to the Portal container when given), exit animations through data-state="closing", and closeOnBack.
