Summary: Adds real-time voice translation, allowing a speaker’s voice to be translated into other languages during a session. Adds greeting audio language support for stream.inviteByPhone() to customize PSTN dial-out greetings. Enables 1080p video resolution in WebRTC mode. Automatic CDN fallback for asset loading, better session join stability, a new dialType property to identify PSTN dial-in or dial-out users, and enhanced audio reliability under poor network conditions. Fixes error with stream.stopAnnotation() on the viewer side and a blank screen issue in stream.startShareView() caused by incomplete state cleanup.
