Reanimated + Skia Performance

Defaults

• Keep animation state on the UI thread: useSharedValue, useDerivedValue, worklets.
• Prefer Reanimated v4 declarative APIs; avoid legacy Animated.
• Prefer shared.get() / shared.set() over shared.value in app code (React Compiler friendly).
• Minimize JS↔UI crossings: avoid scheduleOnRN/runOnJS except for unavoidable side effects.
• For Skia, avoid per-frame React renders: pass SharedValues directly to Skia props/uniforms.
