 * Ask the chat route to prewarm an eve session. The route binds the session
 * to this browser with an httpOnly cookie, so the response carries nothing
 * the client needs to keep; the first message only has to wait for this
 * request so the cookie is in place. Resolves `true` when the route accepted
 * the request and `false` on any failure, which falls back to normal session
 * creation.
