"""Writes web/src/lib/connectors/credentialBoundFields.json.

The file maps each source whose connector config has a ``CredentialBinding``
model to the sorted names of the bound fields. The web create form reads it to
show those fields above the credential section. A backend test compares it
with the binding models.

Usage (from ``backend/``), then format the file with oxfmt:
    python -m scripts.generate_credential_bound_fields
    cd ../web && bun run format
