feat(*): 完善 FANUC J519 闭环、MoveJoint 与现场抓包验证

* 划分 J519 发送循环与稠密轨迹循环职责边界,
  FanucJ519Client 负责 UDP 周期发送,
  FanucControllerRuntime 按轨迹时间更新下一帧命令
* 执行时将规划输出 rad 转为 J519 deg 目标,
  并按 speed_ratio 调整 8ms 发送时间尺度
* 补齐 accept_cmd/received_cmd/sysrdy/rbt_inmotion
  状态位解析与启动前闭环检查
* MoveJoint 改为关节空间直线 + smoothstep 进度
  的临时 PTP 稠密轨迹,按 status=15 运动窗口复现
* 新增 UTTC 2026-04-28 三份抓包 golden tests,
  覆盖 0.5/0.7/1.0 speed_ratio 下的 J519 命令、
  IO 脉冲与响应滞后
* 状态通道补充超时重连策略与退避逻辑
* TCP 10012 命令响应统一检查 result_code
* 状态页扩展 J519 状态位与快照诊断信息
* 新增 docs/fanuc-field-runtime-workflow.md 现场工作流
* 补充 LR Mate 200iD 模型、RobotConfig.json 与 workpiece
