http.Get uses http.DefaultClient, which has no timeout and carries no
context. A backend that accepted the TCP connection but never responded
blocked waitForHealth forever, hanging the launcher with no way to
cancel it -- exactly what the suppressed noctx lint was warning about.
Probe through a package-level client with an explicit 2s timeout using
http.NewRequestWithContext, thread a context down from launcher.Run, and
drain each response body before closing so the connection is reused
across poll iterations. The overall wait now derives a deadline from the
caller's context, so cancellation ends it too.
