## 🔒 Security Fixes

### Prevent Cross-Device Data Leak in Chat Message Queries (#525)
- **Issue**: Device A could potentially read chat history belonging to Device B when they share the same target JID
- **Fix**: Add device_id filtering to message queries with fail-fast validation
- **Impact**: Ensures complete data isolation between devices at multiple layers (usecase, wrapper, and repository)
- **Changes**:
  - Add DeviceID field to MessageFilter struct
  - Require device_id in GetMessages/SearchMessages
  - Add early deviceID validation in GetChatMessages usecase
  - Remove race-prone state mutations in wrapper repositories

## 🐛 Bug Fixes

### React to Other Users' Messages (#535)
- **Issue**: ReactMessage was hardcoded with `FromMe=true`, which only worked for reacting to your own messages
- **Fix**: Look up the message in the database to get the correct `IsFromMe` value
- **Impact**: Users can now properly react to messages sent by others

### Webhook Event Whitelist Filtering (#539)
- **Issue**: After setting whitelist env to just `message`, webhook was still receiving `message.ack` events from groups
- **Fix**: Properly route group events through whitelist filter and fix event name mismatches
- **Impact**: Webhook event filtering now works correctly for all event types
- **Changes**:
  - Fixed event names to match documented names (`message.ack`, `message.deleted`, etc.)
  - Group events now properly go through whitelist filtering
  - Added comprehensive test coverage for whitelist filtering
- **Breaking Change ⚠️**: The `message.deleted` payload structure changed from flat to nested format to align with other webhook events
