Run the required artifact regeneration before the drift check.

Add the rainix-copy-artifacts step sequence in nix develop github:rainlanguage/rainix#sol-shell before this assertion. Then check all generated artifacts, not only subgraph/, for uncommitted drift.

As per coding guidelines: “Regenerate artifacts — run the rainix-copy-artifacts step sequence ... Stage ALL changed artifacts or copy-artifacts drifts red.”

run the required rainix-copy-artifacts sequence within nix develop

generated artifacts rather than only subgraph/.
