langchain-quickjs==0.3.9

### Features

- Configure the number of concurrent subagents with `CodeInterpreterMiddleware(max_subagent_concurrency=16)`. The default remains 32 per REPL; requests above the cap queue until a slot opens. Lower limits can reduce memory use, load, and cost, while higher limits allow more parallel work. The prompt now recommends batches of around 10 rather than requiring them, even at the default setting.
