Both failures showed up as "Test timed out in 30000ms" followed by "Hook
timed out in 30000ms" on loaded PR runners, in files nobody had touched.
relay host-client: the scripted client dialed its WebSocket before awaiting
its WebCrypto setup and only then attached the open/message listeners. On a
loaded runner the loopback socket opened while key generation was still
queued on the threadpool, the open event found no listener, no hello was
sent, and the client waited forever. The socket is now dialed after the key
material is ready, in the same tick as the listeners. The fake relay also
terminates leftover sockets on stop so a failure is reported once, not
twice.
walkthrough routes: each test slept 20 ms and assumed the request had
reached the route by then. The tests now wait until the service has been
asked to generate one more time than before the request, and afterEach
closes idle keep-alive connections so server.close() cannot hang on a
response a failed test never received.
