Subject: [PATCH] launcher: add EnableWindowsTargeting for cross-compile from
 Linux

Microsoft.NET.Sdk.WindowsDesktop emits NETSDK1100 when a Windows-
targeting project is built from a non-Windows host. Setting
EnableWindowsTargeting=true opts in to the cross-compile path, which
works on Linux as long as the WindowsDesktop SDK files are present.

On glados they were copied from a Windows .NET 8 SDK archive into
/usr/lib/dotnet/sdk/8.0.126/Sdks/Microsoft.NET.Sdk.WindowsDesktop/
and /usr/lib/dotnet/packs/Microsoft.WindowsDesktop.App.Ref/. This is
a one-time setup per Linux host -- see the bridge-claude memory note.

No-op on Windows hosts (the flag has no effect when the SDK is native).
Both PC builds and glados builds now produce the same output.
