refactor(web): 适配 ReferencePool 释放及资源管理优化

- Dispose → ReferencePool.Release，new → WebProtoBufData.Create
- 非 WebGL 路径 finally 块补充 ReferencePool.Release
- WebGL 路径重构为 try/finally，确保 UnityWebRequest.Dispose 和
  ReferencePool.Release 始终执行
- 移除共享 MemoryStream 字段，改为每请求独立 MemoryStream 实例，
  消除并发数据竞争和重复 Dispose 问题
- ShutdownProtoBuf 列表清理从 RemoveAt(0) O(n²) 优化为 for 循环
- 移除 WebGL 路径多余的花括号块
