Add visionOS support

[owenselles]

Summary

Port CloudNow to visionOS so users can stream PC games via GeForce NOW in a visionOS window using a connected controller or keyboard/mouse.

What works without changes

• All networking: SignalingClient, CloudMatchClient, GamesClient, ZoneClient, auth
• SDPMunger (pure Foundation)
• GCExtendedGamepad / GCMouse input paths in InputSender
• All non-streaming SwiftUI views (Home, Library, Store, Settings, Login)
• LiveKitWebRTC xcframework — already ships xros-arm64 slices

Required changes

VideoSurfaceView.swift — Full rewrite

layerClass override (AVSampleBufferDisplayLayer as backing layer) is tvOS/iOS-only. Replace with UIView + layer.addSublayer(displayLayer) + layoutSubviews frame management. WebRTCFrameRenderer core is unchanged.

InputSender.swift — Gate Siri Remote path

Wrap GCMicroGamepad, handleMicroGamepad, RemoteInputMode, and touchpad-as-mouse in #if os(tvOS). Extended gamepad + keyboard/mouse paths already work on visionOS.

StreamView.swift — Replace Siri Remote dismissal

.onExitCommand is silently ignored on visionOS. Replace with a SwiftUI .ornament toolbar or tap gesture. Evaluate fullScreenCover → dedicated WindowGroup for the stream.

GFNStreamController.swift — AVAudioSession guards

Gate .moviePlayback / .allowBluetooth options and deprecated requestRecordPermission callback behind #if os(tvOS).

QueueAdPlayerView.swift — Optional

Switch UIViewControllerRepresentable + AVPlayerViewController to VideoPlayer(player:) (5 lines, more idiomatic).

Xcode project + SPM

• Add visionOS deployment target
• Fork livekit/webrtc-xcframework, add .visionOS(.v1) to Package.swift platforms
• Add NSMicrophoneUsageDescription to visionOS Info.plist

Verification

• Build for xrOS Simulator — zero errors
• End-to-end GFN session: video renders, controller input registers
• Overlay show/dismiss works without Siri Remote
• On-device AVSampleBufferDisplayLayer frame rendering confirmed
