feat(apple): stage-2 default + pixel-perfect, decode robustness, UI/rumble polish
Stream reliability
- Default to the stage-2 presenter (VTDecompressionSession + CAMetalLayer): it detects
  and recovers a wedged decoder, where stage-1's AVSampleBufferDisplayLayer freezes hard
  on a lost HEVC reference frame with no app-side recovery (confirmed Apple limitation).
  Stage 1 is now a DEBUG-only presenter toggle, plus the automatic no-Metal fallback.
- Stage-2 pixel-perfect: render the drawable at the decoded size (shader stays 1:1 =
  identity) and let the layer's contentsGravity scale via the system compositor — the
  same path stage-1's videoGravity used — instead of scaling in-shader.
- Loss recovery in both pumps is now a persistent awaitingIDR want, retried until an IDR
  actually lands, so a keyframe request swallowed by the throttle can't strand a frozen
  frame; 100 ms keyframe throttle to match the Android path.
- Fix "Publishing changes from within view updates": defer the HostStore writes out of
  the .onChange(of: model.phase) callback.
- Move AVAudioSession setActive/setCategory off the main thread (async on a shared serial
  queue) to stop the UI-stall warning.

Controllers
- Rumble: capped-exponential backoff when the gamecontrollerd.haptics XPC breaks (-4811)
  so a transient server interruption self-heals instead of cascading; playsHapticsOnly so
  a controller engine doesn't join the always-active streaming audio session.
- Host cards: iPad pointer "magnet" hover effect; iPhone press scale + light haptic.

UI / design
- Ship Geist (SIL OFL 1.1) as the app font (bundled OTFs + registration), with the
  license surfaced in Acknowledgements.
- Restructure iOS/iPadOS Settings into a category NavigationSplitView; resolution wheel
  with custom-resolution entry; 10-bit HDR toggle in Display.
- Industrial host-card redesign (left-aligned, bold, brand monogram tiles).
