## Human Summary
LangGraph SDK version 0.4.13 adds a cancel reason property to Runs and introduces field selection for thread state and history queries.

## Agent Summary
langgraph-sdk 0.4.13 released with new features: Run objects now include a cancel reason, and threads.get state/history endpoints support a select parameter for field projection. Stream docs were also updated.

## Body
LangGraph SDK 0.4.13 (Python) has been released alongside LangGraph core 1.2.20. Key additions include the inclusion of a cancel reason in the Run model (PR 9571) and support for a select argument in threads.get state and threads.get history queries (PR 9568). Documentation was also updated to illustrate the run status in the stream example's end event (PR 9588).

## Recommended actions
- Upgrade langgraph-sdk to version 0.4.13 via package management tooling.
- Optionally leverage the select parameter in threads.get state and history calls to optimize payload retrieval.
- Inspect the new cancel reason field on Run objects when handling run cancellations.
