7308af1c1b Fix web state management: handleInput now returns structured data 
Issues fixed:
- GameSession.handleInput() was returning plain text, causing WebSocket frontend
  to lose state information after each input
- GameWebSocketServer.handleGameInput() was calling unnecessary getStateInfo()
- Duplicate state saves in runCurrentState() and handleInput()

Changes:
1. GameSession.php:
   - handleInput() now returns structured array with output + state info
   - runCurrentState() no longer saves state (already done in handleInput)
   - Consistent return format: { output, state, stateName, playerInfo }

2. GameWebSocketServer.php:
   - handleGameInput() simplified to use handleInput() return value
   - Direct merge of result into WebSocket message

3. web/server.php:
   - handleGameInput() simplified to just return handleInput() result
   - No duplicate getStateInfo() call

Results:
- Web frontend now receives complete state info after each input
- State transitions in submenus now work correctly
- No more state desynchronization between client and server

Testing:
- Input in level 3+ menus now executes correctly
- State name updates properly in header
- Player info (HP, etc) stays synchronized

cf84c53020 Implement WebSocket real-time communication for game 
Replace HTTP API with WebSocket for true real-time bidirectional communication:

Backend Changes:
- Add Ratchet WebSocket library (cboden/ratchet) to composer.json
- New GameWebSocketServer class implementing MessageComponentInterface
  - Handles client connections and session management
  - Message types: login, game-input, sync-state, ping/pong
  - Maintains client connections map and user sessions
- New websocket-server.php startup script
  - Listens on port 9001
  - Uses Ratchet with HttpServer wrapper

Frontend Changes:
- New game-ws.html with WebSocket implementation
  - Replace HTTP requests with WebSocket messages
  - Keep HTTP for authentication (login/register/status)
  - WebSocket handles all game interactions
  - Real-time status display with connection indicator
  - Implements reconnection on disconnect
  - 30-second heartbeat (ping/pong) to maintain connection

Message Protocol:
Client → Server:
  login: { userId, username } - Authenticate and load game
  game-input: { input } - Send game command
  sync-state: {} - Request full state sync
  ping - Heart beat

Server → Client:
  welcome - Initial greeting
  login-success - Auth successful, game loaded
  game-output - Normal command output
  battle-start/end - Battle state changes
  state-sync - Full state snapshot
  error - Error message
  pong - Heartbeat response

Port Configuration:
- HTTP API: port 80 (web server)
- WebSocket: port 9001 (Ratchet server)
- Both services run independently

Usage:
1. Start web server: php -S 0.0.0.0:8080 web/server.php
2. Start WebSocket server: php websocket-server.php
3. Open browser: http://localhost:8080/game-ws.html

Benefits:
✓ True bidirectional real-time communication
✓ Can handle battle interactions in-game
✓ Better for multiplayer scenarios
✓ Persistent connections reduce latency
✓ Future support for spectating, PvP
