UnsupportedVersionException class final

The envelope carries a version other than the one this codec speaks.

genesis_dialogue is strict on version (the wire is pure A2UI v0.9): the field must be present and equal to v0.9. A missing field, or a v0.8 version, is rejected here rather than parsed leniently — silently accepting the wrong version is how a standard rots into a dialect.
