The static catalog alias table (models_catalog_static._PROVIDER_ALIASES, consumed by
parse_model_input / normalize_provider in hermes_cli/models.py) had no entry, so
`/model chatgpt:<model>` and `-m chatgpt:<model>` kept the prefix as part of the model
name while `openai-codex:<model>` split correctly. hermes auth login now falls back to
the shared auth alias table instead of its own 6-entry list (custom providers still win).
Pins providers.normalize_provider('chatgpt') as well and documents the aliases in the
--provider row.
