jupyterlab jupyter-ai GlobalConfig embeddings_fields required field ValidationError

Older notes for jupyterlab__jupyter-ai-1294 can help with context, but they do not fully cover the current failure mode.

Why the common answers are incomplete

Jupyter AI startup can fail with a GlobalConfig ValidationError because embeddings_fields is required but absent in saved config.

Give embeddings_fields a default empty mapping/list or migrate missing config before Pydantic validation.

This issue is about configuration compatibility, so missing embeddings_fields should be treated as older config rather than a fatal user error.
