📝 Feature Summary

Add support for configurable recursion_limit for LangGraph agents

❓ Problem Statement / Motivation

When using KAgentApp with LangGraph, there's no way to configure recursion_limit (max agent steps). LangGraph defaults to 25 steps, which may be insufficient for complex multi-step tasks.

💡 Proposed Solution

Add mechanism to configure recursion_limit in one of the following ways

• KAgentApp constructor: KAgentApp(graph, recursion_limit=50)
• Agent CRD spec: spec.recursionLimit: 50
• environment variable: LANGGRAPH_RECURSION_LIMIT
