Hello, I created a fork to test langgraph_swarm with langchain_core and langgraph >= 1.0.0 because there was this dependency conflict. Then I got an error verifying the active_agent in the workflow creation function. I realised that nowadays the attribute channels is directly inside builder instance, not needing to get from 'schemas'. That´s why I´m creating this PR. Please take a look in this error that is possibly because of the new langraph version.

Eugene Yurtsev (@eyurtsev) Sydney Runkle (@sydney-runkle) Please review, latest version of langgraph-swarm is STILL NOT COMPATIBLE with Langchain v1.0

It would be much appreciated if the developers could update us what the plan is for this - if it is a quick fix or will take some time. Currently trying to work out an upgrade to v1 of langgraph and langchain-core, and this is the only package we use that is currently blocking it. Thanks
