官网下载 APK 直链:强制下载头 + 发布脚本

落地页「官网下载」指向 /media/shaguabijia.apk,但该文件靠手动 cp、且 StaticFiles 给 .apk 的 Content-Type 不对又无 attachment 头,部分国产浏览器不触发下载转甩应用市场。新增 download_apk 路由(挂在静态目录之前),显式回 application/vnd.android.package-archive + Content-Disposition:attachment 强制下载,文件缺失回 404。新增 scripts/publish_apk.sh 把「编 release 包 + 放到 data/media/shaguabijia.apk」固化成一条命令。
