Implement Server-Sent Events (SSE) for real-time battle streaming

Redesign web battle system from buffered to streaming architecture:

Backend Changes:
- New SSEOutput class for real-time event streaming to clients
- GameSession::streamBattle() for SSE-based battle execution
- Enhanced Screen::delay() to support SSE timing and buffering modes
- New /api/game/battle-stream endpoint handling SSE connections

Frontend Changes:
- Enhanced sendInput() to detect battle command (input "1")
- New streamBattle() function using EventSource for SSE connections
- Real-time log display matching terminal experience
- Event handlers for start, message, complete, error events

Benefits:
✓ Real-time streaming instead of waiting for complete battle
✓ Web frontend experience identical to terminal
✓ Lightweight implementation without WebSocket
✓ Automatic browser reconnection support
✓ ANSI colors fully preserved
✓ Backward compatible for non-battle screens
