.SYNOPSIS
    Publishes the Mbproxy binary in two flavours: self-contained and framework-dependent.

.DESCRIPTION
    Produces two single-file builds for the requested runtime under <repo>\publish-out\:

      self-contained\         ~100 MB — bundles the .NET 10 + ASP.NET Core runtime;
                                        no .NET install needed on the target.
      framework-dependent\    ~1.6 MB — requires the .NET 10 + ASP.NET Core runtime
                                        preinstalled on the target.

    The runtime is selected with -Rid (default win-x64). The binary is Mbproxy.exe on
    Windows RIDs and Mbproxy on Linux/macOS RIDs.

    Both builds use the Release configuration and inherit the publish settings declared
    in src\Mbproxy\Mbproxy.csproj (PublishSingleFile=true, SelfContained=true,
    IncludeNativeLibrariesForSelfExtract=true; those settings are gated on an explicit
    RID, which is supplied here). The framework-dependent build overrides
    SelfContained=false on the command line.

.PARAMETER Rid
    .NET runtime identifier to publish for. Examples: win-x64, linux-x64.
    Default: win-x64

.PARAMETER OutputDir
    Root output directory. Two subfolders are created beneath it.
    Default: <repo>\publish-out

.PARAMETER Clean
    Delete OutputDir before publishing.

.EXAMPLE
    .\publish.ps1
    .\publish.ps1 -Rid linux-x64
    .\publish.ps1 -Rid win-x64 -Clean
