Accept dead-ends ( #626 )
...
Previously, we validated that nodes explicitly route to END.
This feels a bit unnecessary, since graphs are expected to keep processing until no work is left to be done
Plus fix a small bug in validation.

Add managed values and IsLastStep ( #330 )
...
* Add managed values and IsLastStep
- managed values are read-only state keys whose values are managed by langgraph
- this PR implements one: IsLastValue, a boolean which is True in the last iteration, eg to allow you to return a nice "ran out of iterations" message to user

Rewrite Graph/StateGraph.compile()
...
- Each iteration of the graph is one single iteration in Pregel (ie. no more "{node}:edges" nodes)
- .update_state() now acts exactly as one of the nodes in the graph (which can be chosen), which makes human-in-the-loop scenarios where you want to override the actions of a specific node a lot easier to build
- Graph/StateGraph.compile() now delegate adding nodes/edges/etc to dedicated methods that operate on the Pregel object, which is 90% of the way towards dynamic graphs where nodes and edges can be added during execution
