Implement offline-first data layer with conflict resolution

[RUKAYAT-CODER]

Background

useOfflineData hook exists but needs enhancement. Implement complete offline-first architecture: persist all data to AsyncStorage, detect offline/online transitions, queue mutations, sync on reconnect with conflict resolution (server-wins, client-wins, manual).

Description

Enhance offline-first data layer with improved conflict resolution and sync strategy.

Current Behavior

Basic offline data persistence. No sophisticated conflict resolution.

Expected Behavior

Complete offline-first: persist, queue, sync with conflict resolution

Impact

📱 App works fully offline
🔄 Seamless sync when connection returns
✨ No data loss

Acceptance Criteria

• Enhance useOfflineData with conflict resolution
• Support conflict strategies: server-wins, client-wins, manual
• Queue mutations when offline
• Sync all changes on reconnect
• Test offline scenarios (disable network)
• Verify no data loss on reconnect
• Document offline-first architecture
• Monitor sync success rates

Implementation Hints

Enhance useOfflineData with versioning/timestamps. Implement conflict resolution handlers. Use AsyncStorage for persistence.

Performance Metrics

Before:

• offlineCapability: Limited

After (Target):

• offlineCapability: Full offline-first with conflict resolution
