Update custom-node-list.json

In v1.0.0 I now strictly enforce a registry-backed whitelist:

    POST /kvtools/peek only serves values for (file_name, key) that exist in kv_registry.json (basename-only, path traversal blocked via abspath().startswith(BASE_DIR)).

    Image serving is scoped to the allowed root (optional extension whitelist), no arbitrary paths.

    UI changes no longer trigger automatic runs.
