+"""Chat startup must explain a mixed-version ImportError (#96900).
+
+A half-updated install can ship a newer ``cli.py`` that imports
+``resolve_turn_limit`` / ``split_model_config_default`` from
+``hermes_cli.config`` while the older ``config.py`` does not export them.
+Construction of ``HermesCLI`` then dies before the agent-setup mixin can
+print ``partial_update_hint``. ``cmd_chat`` is the load-bearing catch:
+bare ``hermes`` and ``hermes chat`` (including the fast-chat launch path)
+all go through it.
