Frame a standalone Server-Sent Events retry: event carrying the
reconnection time in milliseconds (per the SSE standard's retry field:
https://html.spec.whatwg.org/multipage/server-sent-events.html). The server
SHOULD send this before closing a connection it is not terminating; the
client MUST then wait the given number of milliseconds before reconnecting
(basic/transports §Sending Messages item 6). A bare retry: event carries no
data: line, so it updates the client's reconnection time without dispatching
any JSON-RPC payload.
