feat(framework): AppStore + PlatformSession(登录接入)

AppStore(=旧 GameData 子集): setIdentity/setServers/setPhase/applyLogin
- applyLogin 区分两类字段语义:
  * 身份字段(agentid/channelid/agentmode/gameversion)缺省保留旧值
  * 显示字段(agentname)缺省重置为空字符串
- phase 仅由 session 驱动,applyLogin 不写 phase

PlatformSession: 订阅 NetClient 事件总线 → 扇出到三 Store
- 'open' → phase=connected
- 'login'(state==0) → 三 Store 填充 + phase=loggedIn
- 'login'(state!=0) → phase=loginFailed, 不污染 playerid/roomcode
- 'reconnecting' → phase=reconnecting
- 'slow' → phase=slow
- 'kicked' → phase=kicked

110/110 tests pass, typecheck exit 0。
