The prod deploy failed restoring a transitive package
(Microsoft.CodeAnalysis.Workspaces.Common) with NU3008 "package integrity check
failed / has changed since it was signed" — a transient corrupted download on the
build host, not a code change. Wrap the backend `dotnet publish` so that on any
failure it clears all NuGet caches and retries once, re-downloading the package
fresh.
