agentrs-map —— 京东 agentrs 代理网关的「高德地图 / 地理 / 天气」客户端。

封装 6 个高德(Amap)工具：
  poi(POI检索) / geocode(地理编码) / region(行政区) / ip(IP定位) /
  walk(步行路径) / coord(坐标转换)
端点：https://agentrs.jd.com/api/saas/proxy-k/v1/<tool>

鉴权：环境变量 JD_AGENTRS_TOKEN（不硬编码密钥）。
约定：网关一律从 JSON body 取参（query string 不生效）；HTTP 恒 200，业务看 body。

注：天气查询见姊妹 skill agentrs-weather（geocode 拿到的 adcode 即天气入参）。

用法：
  python3 amap.py poi     --keywords 故宫 --city beijing
  python3 amap.py geocode --address "北京市朝阳区建国路88号"
  python3 amap.py region  --keywords 北京 --subdistrict 1
  python3 amap.py ip      --ip 114.247.50.2
  python3 amap.py walk    --origin 116.397455,39.909187 --destination 116.417854,39.914888
  python3 amap.py coord   --locations 116.481499,39.990475 --coordsys gps
