The `get_by_provider_key` method currently uses a linear scan (O(N)) for its slow path when a `provider_key` doesn't match a registry `key`. While this is acceptable for the current number of models, it could become a performance bottleneck as the registry grows.

To optimize this, I suggest creating a reverse lookup map (e.g., `_provider_key_map`) during the registration process. This would make the lookup an O(1) operation, improving both performance and scalability.
