[P1] Consume the actual sealed local API-reference contract

The producer seals the local reference at .castiron/api-definition.yaml in .castiron/generation-inputs.json with a SHA-256 digest; .castiron.stats.yml contains the nested generation-lineage marker, not openapi_transformed_spec_hash. With the actual artifact set, this condition is false, so scripts/mock and scripts/test select the network-backed .stats.yml URL and fail in a hermetic environment. If api_reference/openapi.transformed.yml also exists, awk finds no expected hash and mock startup fails before invoking Steady. Resolve the API-reference path from the canonical generation-input descriptor, verify its SHA-256 and a repo-local regular file, and use the network fallback only when the descriptor/reference pair is absent.

URL="api_reference/openapi.transformed.yml"
EXPECTED_HASH="$(awk '$1 == "openapi_transformed_spec_hash:" { print $2; exit }' .castiron.stats.yml)"
ACTUAL_HASH="$(node -e 'process.stdout.write(require("node:crypto").createHash("md5").update(require("node:fs").readFileSync(process.argv[1])).digest("hex"))' "$URL")"

if [[ -z "$EXPECTED_HASH" || "$ACTUAL_HASH" != "$EXPECTED_HASH" ]]; then
echo "Error: Local OpenAPI specification does not match generation metadata" >&2
exit 1
fi
else
URL="$(grep 'openapi_spec_url' .stats.yml | cut -d' ' -f2)"
