Do you have any suggestions on how to set versioning/branding to get the built SDK to claim that it's preview 1?

The Microsoft built SDK says:

$ dotnet --version
11.0.100-preview.1.26104.118

While building using source-build claims:

$ ./build.sh --prep --source-only
...
$ dotnet --version
11.0.100-dev

Or:

$ ./build.sh --prep --source-only --branding preview
...
$ dotnet --version
11.0.100-dev.final

You would need to provide --official-build-id 20260204.18 (value taken from https://github.com/dotnet/dotnet/releases/download/v11.0.100-preview.1.26104.118/release.json)

Or (I'd assume): --release-manifest release.json
