## Human Summary
LangGraph 1.2.11 adds trace policy configuration on node addition, bumps dependencies including cryptography, and aligns with multiple checkpoint package updates.

## Agent Summary
LangGraph version 1.2.11 exposes trace policy on add node, fixes plain-value seed write collection in checkpoint delta channel history, bumps cryptography to 50.0.0, and includes updates across checkpoint sub-packages.

## Body
LangGraph release 1.2.11 introduces a feature to expose trace policy on the add node functionality ( 8523). It updates dependencies, including a major bump of cryptography from 48.0.1 to 50.0.0 ( 8528) and minor/patch dependency groups. Accompanying checkpoint updates include checkpoint 4.2.0 (with a fix for collecting writes at plain-value seed in delta channel history), checkpoint-postgres 3.1.1 and 3.1.2, and checkpoint-sqlite 3.1.1, alongside linting and conformance test enhancements.
