Subject: [PATCH] fix(camera): drop unused expo-camera; viewfinder crash-safe
 on Android

- remove expo-camera dep (autolink forced CameraX 1.6.0 over vision-camera
  4.7.3's pinned 1.5.0-alpha03, breaking device enumeration on Xiaomi)
- Android: disable Skia frame processor in viewfinder - devices w/o
  hardware-buffered ImageAnalysis frames (Xiaomi 14 Ultra) crash in
  frame.getNativeBuffer(); live filter stays on iOS, filters still apply
  at capture/export
