### archive_doctor.py starts the relay and the room service once before the doctor

- **`wai/quickstart/test/archive_doctor.py`**, run on every release archive and by the Windows
  rehearsal, starts `bin/wai-relay` and `bin/wai-room` once, as `wai doctor` asks them
  (`--version --json`), before it runs the doctor, and prints how long each first start took. The
  first start of a program written moments ago waits on the system's scan of a new executable,
  and that wait counted against the doctor's 6 s for its whole run: on the Windows runner
  (Windows's real-time protection on) a fresh copy of the 0.6.0 release's
  `wai-relay.exe` took 0.4 to 0.7 s to start the first time and 11 to 16 ms the second, and the
  rehearsal's larger debug programs, started first by the doctor on a host its build had just
  loaded, left `stack.wai-relay` and `stack.wai-room` not checked at e694cb096. Every group of the
  doctor's checks that starts no program finished there. A first start that does not end within
  `--timeout` (120 s) fails the check, as a program that hangs.
