test(ui): PlayerInfoView.prefab 复用端到端结构验证

场景层级面板实证(MainMenu.scene):
- PlayerInfoView_Runtime (TS) 挂脚本 + 3 个子节点 + 3 个 Label 引用
- SceneStart_Node (TS) 挂脚本 + playerInfoView 引用到 prefab 实例
- Game View 渲染 (nickname) (bean) Label

结构层面 100% 正确。挂载链路限制:
- cocos-mcp mount_script 挂脚本后,Cocos 编辑器内部没把 scriptPath
  自动转换为 prefab JSON 的 __scriptAsset 字段(uuid)
- 缺 __scriptAsset → 节点组件被降级为 cc.MissingScript
- MissingScript 时 SceneStart.getComponent('PlayerInfoView') 返回 null
  → bindTo 静默跳过,响应式链路无法端到端跑通

修复路径(需用户手动):
1. 在 Cocos 编辑器 UI 内打开 PlayerInfoView.prefab
2. Inspector 拖 PlayerInfoView.ts 到 PlayerInfoView 根节点
3. 保存 prefab → Cocos 自动写入 __scriptAsset

MCP 路径暂时无法跳过这步(无 setter 直接改 prefab JSON)。
