What is the version of langchain-mcp-adapters for which we have approvals? It should appear in the constraints.txt file, but I don't see it.

Context
We upgrade langgraph and langchain to latest versions since versions < 1.0 are being deprecated.
We also need to migrate the code (esp. the agent spec exporter) as langchain's create_react_agent changed a lot.
MCP tool conversion also need to be migrated as they changed the output signature (it now returns a list of content blocks).
