/// The command line a build tool wrapper launch is expected to produce on the current platform.
/// </summary>
/// <remarks>
/// Unix launches go through <c>sh</c>, because a wrapper committed from Windows checks out without an
/// executable bit, so the wrapper path moves from the command into the first argument. Windows launches
/// the <c>.cmd</c> and <c>.bat</c> wrappers through the command interpreter, because a batch file started
/// with redirected stdout can silently produce no output, and runs it through <c>call</c> so the quoted
/// wrapper path is never the first token on a line whose quotes <c>cmd.exe</c> would otherwise strip.
/// <para>
/// Tests state the wrapper, the working directory, and the tool's own arguments, and let this decide the
/// shape, so neither platform is asserted against the other's command line.
