Review Comment:
Could we fetch the SCM pipelines once per attempt and let
`LambdaTestUtils.await` handle `PipelineNotFoundException`? It already retries
exceptions and preserves the last one as the timeout cause. This would remove
the try/catch and redundant null check while keeping the missing pipeline ID
available when the test times out.
