"""A provider registered after ``hermes_cli.models`` was imported still reaches the picker catalog.

``CANONICAL_PROVIDERS`` admitted plugin providers once, at import. A plugin whose imports pull
``hermes_cli.models`` in mid-discovery, or a profile registered at runtime, never reached
``list_available_providers`` / ``_PROVIDER_LABELS`` until restart: the picker twin of the auth
registry window (#102123). ``providers._sync_auth_registry`` now re-admits into both snapshots.
