release: 0.33.0

Minor, not patch: on 0.x the minor is the breaking-change vehicle, and this
release renames the protocol on the wire. `vgi.v2` is now declared rather than
derived from the class name, so a client still addressing `VgiProtocol` is
refused with ProtocolNotSupportedError rather than silently misrouted.
