.SYNOPSIS
构建 Rust ICSP 原生规划库并复制到 src/Libs 与可选目标目录。

.DESCRIPTION
在 Windows x64 上通过 cargo release 构建 flyshot_planning，默认写入
src/Libs/flyshot_planning.dll；Linux x64 写入 src/Libs/libflyshot_planning.so。
可通过 -DestinationDirectories 额外复制到测试或发布输出目录。

.PARAMETER Configuration
传递给 dotnet 相关路径的构建配置名，默认 Release。

.PARAMETER DestinationDirectories
除 src/Libs 外需要覆盖复制的额外目标目录列表。
