test(agents): give the Claude command discovery test's waits a 10 s bound

The test waited 2 s for its Python stub agent to start and to exit. Under a
parallel test run the interpreter's start-up alone can take longer, so the test
failed now and then. Both are polls for a condition, so a longer bound costs
nothing when it passes.
