Configuration based recursion limit is not implemented properly

[avoidwork]

Unhandled rejection: Recursion limit of 25 reached without hitting a stop condition. You can increase the limit by setting the "recursionLimit" config key.

Fixed in PR #254 - #254

The root cause was that recursionLimit from config.yaml was not being threaded through to agent.invoke() and agent.streamEvents(). LangGraph internal config handler defaulted to 25 when the value was not present.

Changes:

• Pass recursionLimit from index.js options to callReactAgent
• Include recursionLimit in config passed to agent.invoke() (non-streaming path)
• Thread recursionLimit through callReactAgentStreaming to streamOptions for agent.streamEvents() (streaming path)
• Added 3 unit tests verifying the threading in both code paths
