chore: 补全工程配置，部署云函数，建立数据库索引

- 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
