Subject: [PATCH] Fix iOS build: use LiveKit 2.15.3 audio API (drop nonexistent
 setEngineAvailability)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The build failed: 'AudioManager' has no member 'setEngineAvailability' — that API
is only on unreleased/main docs, not in the resolved LiveKitClient 2.15.3. Use the
API that actually ships (per audio.md): disable LiveKit's automatic AVAudioSession
configuration (AudioManager.shared.audioSession.isAutomaticConfigurationEnabled =
false) and configure the session ourselves in CXProvider didActivate. Removed all
setEngineAvailability(.none/.default) calls.
