"""Import the pinned upstream mini-AGI code with our own config.yaml.

Upstream reads `config.yaml` from its repo root at call time (minagi.config.DEFAULT),
including from inside the model (peek_experts reads training.chunk). Pointing
DEFAULT at one of our configs makes every upstream call site see the scaled-down
settings without editing upstream files.
