Verified live on Windows: a passed NUnit test under `dotnet test --logger
"console;verbosity=detailed"` prints "Test Run Successful." and "Passed: N",
never the literal "Passed!" the assertion was checking for. Both the native
and managed connector lanes now match the real strings; both were confirmed
to pass for real against a live TypeScript provider (lane 1: 137ms, lane 2:
145ms with the golden-bytes hex line matching the TypeScript peer's own
encoding byte for byte).
