Greptile Summary

This PR updates the langgraph development dependency from version 0.2.76 to 0.6.4, representing a significant jump across multiple minor versions. The change modifies the version constraint in pyproject.toml from ^0.2.62 (caret constraint) to >=0.2.62,<0.7.0 (range constraint).

The langgraph library is used as a development dependency for testing graph-based language processing functionality within the Langfuse Python client. Based on the release notes, the 0.6.x series includes important improvements such as fixes for mypy type checking issues, enhanced subgraph message handling, performance optimizations for checkpoint operations, and deprecation of the MessageGraph class.

The constraint format change from caret to range is significant - the caret constraint (^0.2.62) would have only allowed patch updates within the 0.2.x series, while the new range constraint (>=0.2.62,<0.7.0) permits all minor version updates within the 0.x series up to 0.7.0. This change aligns with Poetry's recommended practices for development dependencies where more permissive versioning is acceptable, and it allows the project to automatically receive future 0.6.x updates while preventing potentially breaking changes from 0.7.x.

Confidence score: 4/5

• This PR is safe to merge with low risk as it updates a development-only dependency
• Score reflects that this is a substantial version jump but limited to dev dependencies with good release notes
• Pay close attention to test results to ensure langgraph integration tests pass with the new version
