After implementing the Streamable transport, it is apparent to me that
the name 'Stream' is confusing, as it can refer either to a stream in
the streamable transport, or to a JSON-RPC stream.
But the name 'Connection' is available, and a natural name for the
result of the Transport.Connect interface method. Therefore, rename
Stream to Connection, and update the streamable implementation to refer
to its HTTP connections as 'streams', consistent with other SDKs.
