refactor: 根包由 com.bestsch.bschclassmanage 重命名为 com.yunhai.bschclassmanage
- git mv src/main/java/com/bestsch/bschclassmanage -> src/main/java/com/yunhai/bschclassmanage - 255 个 Java 文件的 package/import 同步替换为 com.yunhai.bschclassmanage - pom.xml 项目 groupId 设为 com.yunhai（与外部依赖 com.bestsch:bsch-* 无关，未改动） - IDE 缓存 workspace.xml 路径同步更新（外部依赖坐标 com.bestsch:bsch-* 保持不动）
