feat(runtime): 完善 FANUC 命令参数与状态通道重连

* 在 FanucCommandProtocol/Client 中补齐速度倍率、TCP 位姿和
  IO 的封包/解析,并引入 FanucIoTypes 字符串到枚举映射
* FanucControllerRuntime 在非仿真模式下接入真机命令通道,本地
  缓存仅作为兜底,TCP 操作扩展为 7 维 Pose
* FanucStateClient 增加帧超时检测、退避自动重连和诊断状态接口,
  超时或重连期间不再把陈旧帧当作当前机器人状态
* FanucStateProtocol 锁定 90B 帧字段为 pose[6]、joint[6]、
  external_axes[3] 和 raw_tail_words[4],并保留状态字诊断槽位
* ICspPlanner 增加 global_scale > 1.0 失败判定,self-adapt-icsp
  内部禁用该判定以保留补点重试链路
* 同步更新 README/AGENTS/计划文档的 todo 状态和实现说明

2. **性能风险**:同步接口内部阻塞 Socket 可能影响 HTTP 并发。若实测有问题,后续将 `IControllerRuntime` 改为 async。
