langgraph 1.1.4 — LangSmith metadata added, recursion-limit sentinel fix, and deps bumps
LangGraph released 1.1.4 which adds LangSmith integration metadata, fixes a recursion-limit default sentinel collision, and applies dependency bumps (pygments, cryptography, requests). The LangSmith metadata addition surfaces integration/observability metadata from langgraph and the recursion fix reduces potential sentinel collisions when creating agents or runtime graphs.
