Research direction
Start with the three named tests in Aspire.Hosting.CodeGeneration.Go.Tests and inspect how they launch Go subprocesses and apply timeouts. Reproduce the failure on ubuntu-latest using the linked build or the test project, then determine whether the timeout is caused by a shared process-management issue or a specific test path. Done means the affected tests pass reliably in CI.
