RFQ market-maker feed
Role-gated open requests for every quoter plus the quoting maker’s
own state, fill, and finality events, delivered as subscription
frames with params.channel: rfq_maker on the trading connection
after rfq.maker.subscribe. The subscription is per socket and is not
restored by public/session_resume; page rfq.maker.poll on every
connect to recover requests opened while disconnected.
