Implement process-forwarding WebSocket architecture

Browse Source 
New simplified approach: WebSocket server spawns bin/game process and forwards I/O

Backend Changes:
- New GameProcessServer class (src/Core/GameProcessServer.php)
  - Implements MessageComponentInterface (Ratchet)
  - For each WebSocket connection, spawns independent php bin/game process
  - Uses proc_open() to manage process I/O pipes
  - Reads process STDOUT/STDERR in non-blocking mode
  - Writes client input to process STDIN
  - Automatic process cleanup on disconnect
  - No game code modifications required

- New websocket-process-server.php startup script
  - Listens on port 9002
  - Simple process forwarder without game-specific logic
  - Suitable for any interactive CLI application

Frontend Changes:
- New web/process.html
  - Ultra-simple WebSocket frontend for process I/O
  - Direct STDIN/STDOUT forwarding
  - ANSI color support via xterm.js
  - Minimal dependencies, minimal code
  - Suitable for any CLI game/application

Architecture Benefits:
✓ Zero game code changes needed
✓ Each user gets independent process (isolation)
✓ Real process STDIO, not emulation
✓ ANSI colors work perfectly
✓ Can run ANY CLI application (not just this game)
✓ Simpler than GameSession-based approach
✓ Easier to deploy and manage

Usage:
1. Start WebSocket server:
   php websocket-process-server.php

2. Start HTTP file server (for static files):
   php -S 0.0.0.0:8080 web/server.php

3. Open browser:
   http://localhost:8080/process.html

Message Protocol:
Client → Server:
  { "type": "input", "input": "command" } - Send stdin to process
  { "type": "ping" } - Heartbeat

Server → Client:
  { "type": "output", "text": "..." } - Process stdout/stderr
  { "type": "system", "message": "..." } - Server messages
  { "type": "error", "message": "..." } - Error messages
  { "type": "pong" } - Heartbeat response

Features:
- Non-blocking I/O reading
- Stream buffering management
- Automatic reconnection support
- 30-second heartbeat for keep-alive
- Process termination on disconnect
- Proper error handling

This is the simplest and most elegant approach for running CLI games on web!

⚡ WebSocket 服务器启动
📍 地址: 0.0.0.0:9002
🔗 客户端连接: ws://localhost:9002
📋 运作原理:
1. 为每个WebSocket连接启动一个 php bin/game 进程
2. 实时读取进程的STDOUT/STDERR
3. 通过WebSocket发送给客户端
4. 客户端输入直接写入进程的STDIN
💡 特点:
✓ 无需修改游戏代码
✓ 每个用户独立的游戏进程
✓ 完整的ANSI颜色支持
✓ 实时交互
