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。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
