v0.3.1

What's new

• Fix: crash on session RPC to a downed distributed node — a GenServer.call to a session living on a node that has left the cluster (e.g. mid-deployment, or a node disconnect) exits with {{:nodedown, node}, _}. This was not caught by the transport and crashed the request process. It now degrades to a 404 instead of propagating the crash, and any other unexpected exit is logged and handled the same way. Thanks to @ryancurtin for the report and fix (#1).
