#134320 registered ProviderProfiles for lmstudio and tencent-tokenhub without env_vars. That put
both into the provider-catalog E2E matrix for the first time with key_env=None. The shard fixture
then died on keys[""] (KeyError, every row of the shard errored), TokenHub turns could not find a
key, and LM Studio's /model switch could not reach the native /api/v1/models listing the fake
never served.
The profiles now name the same env vars their hermes_cli/auth.py registry rows use (that row stays
the lookup source of truth). The catalog fake also answers LM Studio's native listing.
