feat: 接入 VizieR 星表检索与 LAMOST/Gaia/SDSS/DESI 跨源光谱下载
新增天文观测数据获取能力，覆盖星表查询与一维光谱下载两大场景：
星表检索（CDS VizieR）
- VizieR TAP 客户端（JSON 优先 + VOTable 降级），共享 IVOA VOTable 解析层
- 业务层支持自由 ADQL、锥形检索、交叉证认、星表发现与 CSV 导出
- ADQL 注入防护（标识符清洗 + 字符串字面量转义），TTL 缓存（7 天）
跨望远镜光谱下载（统一入口）
- 接入 LAMOST（ConeSearch + FITS.gz）、Gaia（TAP + DataLink ZIP）、
SDSS（Data Lab TAP + SAS）、DESI（HEALPix coadd）四源
- 双模式：坐标模式（cone 检索 → 选源 → 下载）/ 标识符模式（直按 ID 下载）
- 光谱文件永久缓存（不可变），按 source+source_id 去重
Agent 与 API
- +4 工具：query_vizier / cone_search / find_spectrum / catalog_operation（22 → 26）
- +6 路由：/catalog/vizier、/cone、/crossmatch、/spectrum/{download,list}
- 前端新增 VizierResultCard / FindSpectrumCard 可视化卡片
工程重构
- services/target.rs (832 行) 拆分为 services/cds/{target,vizier}.rs + clients/cds/sesame.rs，
贯彻 client（通信）/ service（缓存+编排）分层
- ADS 返回字段新增 data（关联数据表 URL），与星表功能联动

# VizieR 星表查询指南
|
||||
|
||||
## 表名结构
|
||||
|
||||
VizieR 表名三段式：`分类/编号/子集`
|
||||
|
||||
```
|
||||
I/355/gaiadr3
|
||||
│ │ │
|
||||
│ │ └─ 子集：具体数据子集或版本
|
||||
│ └───── 编号：CDS 分配的顺序号（纯索引）
|
||||
└──────── 分类：数据类型
|
||||
```
|
||||
|
||||
### 分类前缀
|
||||
|
||||
| 前缀 | 类型 | 说明 | 示例 |
|
||||
|------|------|------|------|
|
||||
| `I/` | 天体测量 | 位置、自行、视差 | `I/355/gaiadr3`（Gaia DR3） |
|
||||
| `II/` | 测光 | 多波段测光数据 | `II/246/out`（2MASS） |
|
||||
| `III/` | 光谱 | 已发布光谱 flux 数据 | `III/272`（LAMOST DR6） |
|
||||
| `IV/` | 交叉证认 | 不同星表匹配结果 | `IV/14/trp2mass` |
|
||||
| `V/` | 综合 | 大型巡天综合目录 | `V/162/dr11l`（LAMOST）、`V/154/sdss16`（SDSS） |
|
||||
| `B/` | 文献（旧） | 早期文献伴生数据 | `B/cb/cbdata` |
|
||||
| `J/` | 期刊表 | 论文伴生数据表 | `J/ApJ/836/5/table1` |
|
||||
|
||||
### 为什么 LAMOST 和 SDSS 是 `V/` 不是 `III/`
|
||||
|
||||
`III/` 要求表中直接包含光谱 flux 数组（波长-流量对）。LAMOST 和 SDSS 的 VizieR 表只存了测光/元数据/参数，原始光谱 FITS 文件在各自数据中心，所以归入 `V/`（综合巡天目录）。
|
||||
|
||||
### `J/` 期刊表命名
|
||||
|
||||
```
|
||||
J/ApJ/836/5/table1
|
||||
│ │ │ │ │
|
||||
│ │ │ │ └─ 论文中表编号
|
||||
│ │ │ └───── 卷号
|
||||
│ │ └───────── 文章编号
|
||||
│ └────────────── 期刊缩写
|
||||
└───────────────── 固定前缀 J/
|
||||
```
|
||||
|
||||
常用期刊：`ApJ`（天体物理学报）、`A&A`（天文与天体物理）、`MNRAS`（皇家天文学会月刊）、`AJ`（天文期刊）、`ApJS`（天体物理学报增刊）
