feat(ios): ship iOS SwiftUI client (VoiceCatiOS)

Full SwiftUI app at clients/apple/iOS/VoiceCatiOS.xcodeproj: - 24 Swift source files: AppState + SessionState (@Observable @MainActor), AudioSessionManager (AVAudioSession owner + interruption/route handling), ServerListStore/SavedServer (App Group container + Keychain sharing), and 14 SwiftUI views covering the full feature set - NavigationSplitView on iPad, TabView on iPhone (horizontalSizeClass) - Channel tree via OutlineGroup, user list with context menu admin actions - PTT via DragGesture(minimumDistance: 0) + @GestureState - onEvent closures hop to MainActor via Task { @MainActor in ... } - App Group: group.cat.voice.VoiceCat (shared with future ReplayKit extension) C ABI: add vc_audio_suspend / vc_audio_resume (AudioEngine::suspend/resume) called by AudioSessionManager on AVAudioSession interruption events. XCFramework: add ios-arm64 and ios-arm64-simulator slices to build-xcframework.sh; Package.swift gains .iOS(.v17) platform; CMakePresets.json adds apple-ios / apple-ios-sim presets with arm64-ios / arm64-ios-simulator vcpkg triplets. Verified: xcodebuild -target VoiceCatiOS -sdk iphonesimulator26.5 BUILD SUCCEEDED.
