  <!-- nucleic-brokerd (docs/WINDOWS_PORT.md §2.3, §3.3): the C# child process of
       nucleic-hostd that owns every Microsoft.WSL.Containers (wslc) call, exposed to Swift
       as NDJSON JSON-RPC 2.0 over stdio.

       The wslc WinRT surface is isolated behind IWslc, and the REAL facade is compiled only
       when -p:UseWslc=true (a Windows machine with the preview NuGet reachable): the API is
       public preview with breaking changes expected, and the M1 spike validates it. Every
       other build — Linux CI, the fake-backed unit tests — compiles the portable core plus
       an "unavailable" facade, so broker logic and RPC surface are testable everywhere. -->
