feat: alias error types through the wl shim

The shim aliased every type a caller needs except the ones used to describe a
transport failure, so classifying an error meant importing the root package
alongside it. DisplayError, ProtocolError and the four sentinels are now
re-exported, and errors.Is works through the shim.
