feat(scripts): LoginFlow 接入 PlatformSession + NetClient (setIdentity 修复)

真机端到端验证场景流程(07:24:55):
[LoginFlow] constructing NetClient with servers=ws://mock
[LoginFlow] net.start() called
[LoginFlow] bus.on(open) fired
[LoginFlow] bus.on(login) fired, state=0
[LoginFlow] login success, phase=loggedIn
[LoginFlow] RoomRPCBus started
[SceneStart] bindTo 已触发

修复 NetClient.setIdentity 缺漏(原 login 事件不触发):
- 之前 NetClient.start() 调 sendLogin → identity null 早返
- isSendLoginState 仍 false → bus.on('login') 永不触发
- 修复:NetClient 构造后立即 setIdentity(mock 身份)

真机端到端验证 Loading → Login → 模拟登录成功 → loadScene('MainMenu')。
C 规范 §6.1 启动流程的 [NetClient + PlatformSession + RoomRPCBus] 链跑通。

 /**
- * LoginFlow: 登录场景编排器（仿 gameabc 启动流程 step 3）。
+ * LoginFlow: 登录场景编排器(真机版,接入 PlatformSession 真实流)。
  *
- * 完整流程(后续接入 PlatformSession 后实现):
- * 1. 显示 Login_Layer prefab(微信/手机/游客登录按钮)
- * 2. 用户点击「游客登录」按钮 → PlatformSession.startup() 触发
- * 3. bootstrap + WS connect + login 成功后,AppStore.phase = loggedIn
- * 4. director.loadScene('MainMenu')
+ * 流程(对应 gameabc 启动流程 step 3):
+ * 1. 构造 EventBus + PlatformSession + NetClient(用 mock transport)
+ * 2. 调 resolveBootstrap 拉远程配置(可能因无后端失败 → 进 loginFailed)
+ * 3. Mock transport 同步触发 open + login 事件 → PlatformSession 落 Store
+ * 4. login 成功(state=0) → AppStore.phase=loggedIn → director.loadScene('MainMenu')
  *
- * 当前简化:2 秒后自动跳到 MainMenu,验证场景切换链路。
+ * 注意:当前 Transport 是 mock sync 触发(真 WS 需要 Cocos WebSocket adapter,
+ * 未实现)。framework/net/cocos-transport.ts 留作生产占位。
+ *
+ * 限制:PlayerInfoView prefab 持久化 __type__ 字段问题未解决(memory 记录),
+ * 本脚本不依赖 PlayerInfoView 组件,只验证 PlatformSession 链路。
