test(code-runtime-python): exempt the mid-drain settle branch from coverage

The drain loop's `if (settled) break` needs the run to settle in the window between two queued frames. A file probe on the concurrent-replies case shows the queue does reach depth 11, but the wall clock never lands inside that window, so the branch is not schedulable from a test; a case written to force it passed without ever executing the line, so it is removed rather than left as coverage it does not provide. The branch carries a v8 ignore naming what is unreachable.
