uts-proxy v0.3.0 (ably/uts-proxy#4) derives a WebSocket message's encoding from the `format` query parameter — matching the Ably server — rather than from the WebSocket frame type. The proxy can therefore decode and match both JSON and msgpack messages, including SDKs (e.g. ably-java) that send JSON payloads over binary WebSocket frames.

Update proxy to reflect the actual server logic: the message type is defined by the format parameter, not by the type of the WebSocket frame.
