Release 2.6.0

Added

• Ad push opt-out ("수신거부") action. Push notifications carrying an unsubscribe_url custom-data field are treated as ad pushes and now expose a "수신거부" action on long-press; tapping it opens the unsubscribe_url (custom scheme deep link or web page). The SDK registers the NOTIFLY_AD notification category — merged with any categories the host app already registered — and handles the action tap. The cold-start case is covered: the tapped action identifier is cached so that, when the app is launched from a kill state by the opt-out tap, it navigates to the unsubscribe destination rather than the notification's content URL.
  • Requires the server to deliver ad pushes with aps.category = "NOTIFLY_AD" (alongside the unsubscribe_url custom data).
