Program.cs is a top-level-statements file: every type declaration (the
existing ServeConfig, DialConfig and friends) lives after every top-level
statement and local function, all clustered at the end. The new record landed
between two local functions instead, which is CS8803: "top-level statements
must precede namespace and type declarations." Moved beside DialConfig, where
its neighbors already live.
Found by a direct `dotnet build` run on Yggdrasil after the interop test's own
error message was truncated by Node's console printing before reaching the
actual compiler diagnostic.
