testRuntime() previously called wait(for:timeout:) with a single 300s budget. If the runtime crashed (EXC_BAD_ACCESS or similar) the HTTP POST that fulfills runtimeUnitTestsExpectation never arrived, so the test would sit out the full 5 minutes before reporting a generic timeout — masking crashes as slow tests in CI. Add a 0.5s polling Timer that watches XCUIApplication.state and fulfills the expectation when the app reaches .notRunning, recording the exit via a didCrash flag. The Timer is registered on RunLoop.main in .common modes so it keeps firing while XCTWaiter spins the run loop. After the wait resolves, didCrash drives a specific XCTFail pointing reviewers at ~/Library/Logs/DiagnosticReports/TestRunner-*.ips, while a true timeout still surfaces as the original "exceeded N seconds" failure. Switching the expectation from self.expectation(...) to a standalone XCTestExpectation is required because XCTestCase tracks the former and requires waitForExpectations; driving it through XCTWaiter directly avoids that constraint.
