feat(apple): tvOS client — third app target, first-lit in the Apple TV simulator

The same app now runs on tvOS (target Punktfunk-tvOS, bundle io.unom.punktfunk.tvos),
validated live against the box: vkcube at 1280x720@60, 60 fps in the Apple TV 4K
simulator, glass HUD with a focusable Disconnect button.

- PunktfunkCore.xcframework grows tvOS device + universal-simulator slices. These are
  TIER-3 Rust targets (no prebuilt std): BUILD_TVOS=1 builds them with nightly and
  -Zbuild-std from rust-src — the full quic stack (quinn/rustls-ring/tokio) compiles
  for tvOS unchanged.
- The UIKit stream view covers iOS AND tvOS, with pointer interaction, pointer lock,
  touch forwarding and InputCapture gated to iOS — tvOS is view-only until gamepad
  capture lands (the natural tvOS input).
- SessionAudio on tvOS: .playback session, no mic (no app-accessible microphone).
- App chrome gates: keyboardShortcut/textSelection/controlSize/statusBarHidden are
  iOS/macOS-only; host cards use the focus-native .card button style on tvOS; the
  Audio settings section hides (system-routed); mode seeding works from the TV screen
  (1920x1080@60).
- Package platforms += .tvOS(.v17); new Xcode target + shared scheme
  (TARGETED_DEVICE_FAMILY 3, local-network usage description included).
