M3(批4): 图片/摇一摇/扫码/相机/定位 Provider
T-M3-07 PhotoProvider：getphoto 批量下载到资源根 photos/(file:// 白名单内) → 出站 getphoto[{pid,photourl}]，复用 Downloader 并行
T-M3-08 ShakeProvider：startshake/SwitchShake/stopshake，@ohos.sensor 加速度合力阈值检测+节流，~1s 后出站 shakeEnd(空串)，反馈震动
T-M3-11 ScanProvider：opensaoma → @kit.ScanKit 默认界面扫码(免权限) → 出站 getsaomaData(originalValue)
T-M3-12 CameraProvider：opencamera → @kit.CameraKit cameraPicker.pick(免权限) → 出站 getcameraaAddress(resultUri)
T-M3-09 LocationProvider：startlocation(连续/单次,用时申请权限)/getlocationinfo(同步) → geoLocationManager 定位+逆地理编码 →
出站 getlocationinfo(MaplocationInfo；错误码 0/-1未就绪/-2权限拒绝)
module.json5 增 ACCELEROMETER/LOCATION/APPROXIMATELY_LOCATION；组装根装配 5 者
devecocli build 通过。

* - startlocation：data="1" 连续 / 其他 单次。用时申请定位权限；定位成功逆地理编码后出站 getlocationinfo。

* - getlocationinfo：同步返回最近一次 MaplocationInfo（未就绪 errorCode=-1 / 权限拒绝 -2）。

* 需 module.json5 声明 LOCATION + APPROXIMATELY_LOCATION，运行时申请。
