Bumps langgraph from 1.2.11 to 1.2.18.

Release notes

Sourced from langgraph's releases.

langgraph==1.2.18

Changes since 1.2.17

• release(checkpoint): 4.3.1 (#9447)
• release(langgraph): 1.2.18 (#9445)
• fix(langgraph): let error_handler recover on every path and stream failed task results (#9408)
• feat(langgraph): default delta snapshots to 100 updates (#9420). DeltaChannel now takes a full snapshot every 100 updates instead of 1000: faster reads on long threads, more storage. Pass snapshot_frequency=1000 to keep the old behavior.
