1. 修复 `Utils.getStopTime` 和 `Utils.getNextStation` 会误匹配“非车站指令”（如修改最高速度等指令）中的文本的问题，现在仅在 `instruction.id == create:station` 或 `create:destination` 的条目中扫描，保证了 CC 电脑从 `create:track_station` 获取到的时刻表信息（包括计算出的停站时间）100% 准确。 2. 修复显示器（Display Board / NBT）在列车停站后依然显示“离站倒计时 ETA”，导致触发 `train_approaching` 的问题：如果当前列车已经在站内（`State.currentTrain` 存在且匹配），将强制忽略该列车的 `train_approaching` 触发逻辑，彻底解决列车停站时倒秒导致的重复播报。
