# package.sh — 编译并把 wind_power 产物整理到 runtime/wind_power/
#
# 输出目录结构：
#   runtime/wind_power/
#   ├── wind_server            # 后端可执行
#   ├── config/                # server_config.json 等静态配置
#   ├── web/                   # 前端静态资源（vite build 产物）
#   ├── libs/                  # 运行期依赖库（libdrogon/libtrantor .so）
#   └── logs/                  # 日志目录（运行时写入）
#
# 用法：
#   ./package.sh                         # 默认 Release
#   ./package.sh --build-type Debug
#   ./package.sh --publish               # 额外打包到 publish/wind_power-<ver>.tar.gz
#
# 参考: edge_collector/package.sh
