[Adapter] LangGraph export/runner

[shreyas-lyzr]

Summary

Add a LangGraph adapter to gitagent, enabling export and run support for the LangGraph framework.

Details

LangGraph is a popular framework for building stateful, multi-agent applications with LLMs. A gitagent adapter would allow users to:

• Export: Convert a gitagent agent definition to a LangGraph graph/state machine
• Run: Execute a gitagent-defined agent using the LangGraph runtime

Acceptance Criteria

• gitagent export --format langgraph generates valid LangGraph Python code
• gitagent run ./agent --adapter langgraph executes the agent
• Documentation added to README adapter table
• Example added to examples/

Resources

• LangGraph docs
• Existing adapters in src/adapters/ for reference

DeepAgent instead.

Hi @shreyas-lyzr, you mentioned DeepAgent as a potential alternative.

Could you clarify:

1. Is the current LangGraph PR complete or does it need work?
2. Should we pursue DeepAgent implementation instead of LangGraph?
3. If DeepAgent is preferred, would you like me to work on that adapter?

I'd be happy to help implement whichever approach you think is best.
