chore: bump version to 1.9.0

- Added tracking of online users with real-time status updates (online/offline).
- Implemented `handleTyping` to broadcast user typing events to recipients.
- Added `check_status` handler to query user online status.
- Enhanced CORS configuration to support multi-domain deployments with credentials.
