The source registry is registry/manual.json. Add or update chains there.
Do not edit src/generated/ or assets/chains.json by hand.
Run uv run python scripts/update-registry.py after registry changes. The script regenerates Rust plus JSON artifacts from the manual registry.
Keep generated outputs committed with the manual registry change.
