 /**
  * Base DialogFragment with ViewBinding support and single-shot ViewModel event collection.<br>
  * Manages binding lifecycle safely and resets onDestroyView().<br><br>
  * ViewBinding 지원과 단일 ViewModel 이벤트 수집을 제공하는 기본 DialogFragment입니다.<br>
  * 바인딩 생명주기를 안전하게 관리하고 onDestroyView()에서 초기화합니다.<br>
  *
  * **Key points:**<br>
  * - Call super.onViewCreated().<br>
  * - onEventVmCollect() is invoked once after binding initialization.<br>
  * - In DialogFragment, keeping the default `false` for isAttachToParent is recommended unless there is a verified special case.<br><br>
  * **핵심 포인트:**<br>
  * - super.onViewCreated()를 반드시 호출하세요.<br>
  * - onEventVmCollect()는 바인딩 초기화 이후 1회 호출됩니다.<br>
  * - DialogFragment에서는 특별한 경우가 아니라면 isAttachToParent의 기본값 `false` 사용을 권장합니다.<br>
  *
  * @param BINDING The type of ViewBinding to be used.<br><br>
  *                사용할 ViewBinding 타입.<br>
