- 新增 .gitignore（排除 node_modules、私有配置、编译产物） - 新增 cloudbaserc.json，绑定云环境 cloud1-d4g697lte499543d8 - project.config.json：补 miniprogramRoot、开启 useCompilerPlugins typescript，修复预览报 app.json 找不到的问题 - tsconfig.json：移除无效 typeRoots，解除 TypeScript 编译阻断 - miniprogram/app.json：移除 glass-easel（需基础库 3.x，兼容性差） - miniprogram/utils/constants.ts：填入真实云环境 ID - cloudfunctions/updateLocation：位置字段改用 GeoPoint 以支持地理索引 - cloudfunctions/getNearbyPets：改用 geoNear 聚合管道，支持真实距离排序 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
