- 定位插件新增 getCurrentPlace：安卓高德定位（华为上高德只回坐标时退回系统 Geocoder），
iOS CoreLocation + CLGeocoder；不在插件里弹权限框，失败回原因
- DeviceLocationService：启动/回前台刷新、10 分钟节流、落盘缓存；香薰首次连上（前台）申请一次
「使用期间」定位权限，拒绝后不再追问；建会话只读缓存，不拖慢唤醒
- BailianMultimodalService.start：仅对登记的应用（车载香薰）带
client_info.location{latitude,longitude,city_name} 与 biz_params.user_prompt_params{location,date}，
date 精确到分；拿不到地名时用坐标描述。EMAI 耳机的 Start 报文不变
