fix: 修复3D地球坐标映射多个严重bug
## Bug修复详情 ### 1. 致命错误：球面距离计算 (calculateDistance) - 问题：使用勾股定理计算经纬度距离，在球体表面完全错误 - 修复：改用Haversine公式计算球面大圆距离 - 影响：赤道1度=111km，极地1度=19km，原计算误差巨大 ### 2. 经度范围规范化 (vector3ToLatLon) - 问题：Math.atan2返回[-180°,180°]，转换后可能超出标准范围 - 修复：添加while循环规范化到[-180, 180]区间 - 影响：避免本初子午线附近返回360°的异常值 ### 3. 屏幕坐标转换支持非全屏 (screenToEarthCoords) - 问题：假设Canvas永远全屏，非全屏时点击偏移严重 - 修复：新增domElement参数，使用getBoundingClientRect()计算相对坐标 - 影响：嵌入式3D地球组件也能精准拾取 ### 4. 地球旋转时经纬度映射错误 - 问题：Raycaster返回世界坐标，未考虑地球自转 - 修复：使用earth.worldToLocal()转换到本地坐标空间 - 影响：地球旋转时经纬度显示正确跟随 ## 新增功能 - CelesTrak卫星数据采集器 - Space-Track卫星数据采集器 - 卫星可视化模块（500颗，实时SGP4轨道计算） - 海底光缆悬停显示info-card - 统一info-card组件 - 工具栏按钮（Stellarium风格） - 缩放控制（百分比显示） - Docker volume映射（代码热更新） ## 文件变更 - utils.js: 坐标转换核心逻辑修复 - satellites.js: 新增卫星可视化 - cables.js: 悬停交互支持 - main.js: 悬停/锁定逻辑 - controls.js: 工具栏UI - info-card.js: 统一卡片组件 - docker-compose.yml: volume映射 - restart.sh: 简化重启脚本
