✨ feat(compat): 补齐飞拍执行等待与 FANUC 状态驱动链路

- 为 ExecuteFlyShotTraj 补齐 wait 语义，并让 move_to_start
  先完成临时 PTP 运动后再启动正式飞拍轨迹
- 将 J519 命令发送改为由机器人 UDP status sequence 驱动，
  避免在未收到状态包时主动发周期命令
- 将 10010 状态通道关节字段统一按 JointRadians 命名，
  同步更新运行时读取逻辑与协议测试
- 新增 FANUC 10010 状态帧、流运动手册和 Python client
  逆向文档，并更新 README 与兼容需求说明
- 补充兼容层编排测试与 HTTP 集成测试，覆盖 wait 和
  move_to_start 串行化行为
