## Human Summary
LangGraph 1.2.17 patches recursion limit handling and preserves caller namespaces during RemoteGraph subgraph streaming.

## Agent Summary
LangGraph release 1.2.17 resolves recursion limit defaults, fixes namespace preservation in RemoteGraph.stream(subgraphs=True), and updates dependency constraints.

## Body
LangGraph version 1.2.17 includes bug fixes and dependency updates since 1.2.16. Key changes include explicitly applying a recursion limit equal to the default, ensuring the caller's namespace is maintained when calling RemoteGraph.stream(subgraphs=True), removing precautionary third-party upper bounds, and updating internal dependencies such as certifi and dev packages.

## Recommended actions
- Upgrade to langgraph==1.2.17 if relying on RemoteGraph subgraph streaming or default recursion limits.
