Overview

Routes a WebSocket upgrade to a handler by the version subprotocol it advertises, falling back to default (v2) when none matches — the forward-compatible seam for registering future protocol versions. Same Rack-endpoint shape as Dispatcher, so Rails match to: hands the connection off correctly in production.
