🎯 Goal

Remove the third-party react-native-haptic-feedback and expo-haptics dependencies and replace them with a built-in native module. This reduces the number of external dependencies the SDK relies on for haptic feedback.

🛠 Implementation details

Follows the existing shared-native/ pattern (same as StreamVideoThumbnailGenerator):

• iOS (Swift): StreamHapticFeedback.swift — uses UIImpactFeedbackGenerator, UINotificationFeedbackGenerator, and UISelectionFeedbackGenerator to provide all haptic types (impactLight, impactMedium, impactHeavy, notificationSuccess, notificationWarning, notificationError, selection).
• iOS (Obj-C bridge): StreamHapticFeedbackModule.m — exposes the Swift implementation to React Native via RCT_EXPORT_MODULE. Dispatches to main thread since UIFeedbackGenerator requires it. Works on both old and new architecture.
• Android (Kotlin): StreamHapticFeedback.kt — uses View.performHapticFeedback() with HapticFeedbackConstants, with API 30+ aware fallbacks for CONFIRM/REJECT constants.
• Android modules: Registered in both StreamChatReactNativePackage and StreamChatExpoPackage.
• JS layer: Both triggerHaptic.ts files (native-package and expo-package) now call NativeModules.StreamHapticFeedback instead of the third-party libraries.

The registerNativeHandlers pattern is preserved — users can still override or disable haptic feedback via registerNativeHandlers({ triggerHaptic: () => {} }).

No changes to the core package (package/src/) — all component call sites remain unchanged since they access haptics through NativeHandlers.triggerHaptic().

🎨 UI Changes

No visual changes. Haptic feedback behavior is functionally equivalent to the previous implementation.

🧪 Testing

• yarn build passes cleanly
• yarn lint passes with 0 warnings
• yarn test:unit — all haptic-related tests pass (MessageReactionPicker: 6/6). Only pre-existing failures remain (SQLite Node.js version mismatch, Gallery timeout)
• Manual testing needed on physical devices for haptic feedback in:
  • Message long press (MessageBubble — impactMedium)
  • Reaction picker (MessageReactionPicker — impactLight)
  • Audio recording start/stop (AudioRecordingButton — impactHeavy, notificationSuccess, notificationError)
  • Audio recorder state changes (AudioRecorder — impactMedium)
  • Image gallery pinch zoom limits (useImageGalleryGestures — impactLight)
