✨ feat(flyshot): 引入飞拍执行侧最终发送队列构建与校验机制

* 新增 FlyshotExecutionSendSequenceBuilder，负责在运行时前构建最终 8ms 发送队列，并进行离散限幅校验。
* 引入 FlyshotPreparedExecution 类，封装最终发送结果及相关诊断信息。
* 调整 ControllerClientCompatService 和 FanucControllerRuntime，确保运行时直接使用预生成的发送队列，避免临场重采样。
* 更新 TrajectoryResult 和 PlannedExecutionBundle，支持准备好的执行队列。
* 增加单元测试，验证非 1 倍 speedRatio 下的执行行为与预生成队列的使用。
