feat: 完善星表查询与跨版本回归验证

- 将星表名称数据收敛为 TSV/GZIP 单一数据源，补充中文名、别名、英文常用名及宿/垣区域字段
- 增加星表名称表加载校验、旧详情字段一致性校验和 GZIP 漂移检查
- 新增 StarDataByName、StarDataByNameAll、StarDataByNameIn ，统一中英文查询与重名消歧
- 优化日月食半影带、升落曲线和可见性回归测试，补充极区、拓扑及低精度场景覆盖
- 增加 Go 1.16/386 兼容门禁和测试案例，处理旧工具链的分配、拓扑、SVG字节及 ULP 差异
- 补充星表、坐标、日月食和低精度回归用例，完善测试文件与缓存忽略规则
