🤖 Fix(jest): ESM provider preload caused Integration Test failures\n\n- Prefer CJS require for @ai-sdk/{anthropic,openai} in tests; fall back to ESM\n- Dual-import in createModel to work in both Jest (CJS) and prod (ESM)\n- Keep prod behavior unchanged; only short-circuit preload under Jest\n\nGenerated with
