feat: Implement network battle and practice modes with question generation
- Added `questionGenerator.ts` for dynamic question generation based on difficulty levels. - Created `NetworkBattle.vue` for real-time multiplayer gameplay using PeerJS. - Developed `Practice.vue` for single-player practice sessions with score tracking and history. - Updated `yarn.lock` to include new dependencies for PeerJS and message packing. - Enhanced UI with responsive design and feedback animations for user interactions.
