Research direction
Read src/meridian/adapters/langgraph_adapter.py and find the existing adapter tests and test conventions. Use a fake graph with ainvoke to check that its final state maps to the expected AdapterResult, then check that a target without invoke or ainvoke raises AdapterSpecError. Done when both paths pass on the host without LangGraph installed.

Description
Context
adapters/langgraph_adapter.py has no unit coverage. It only needs an object with ainvoke, so a fake graph works without installing LangGraph.
What to do
Test: a fake graph's final state maps to the right AdapterResult; a target without invoke/ainvoke raises AdapterSpecError.
Done when
Both paths are tested on the host.
Where to look
