Remove noisy frames from stack traces
...
- The less frames in library code the less confused the user is
- This doesn't remove all library frames (not possible), but it's a start

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

Add stream_mode=updates or values
...
- stream(stream_mode="values") yields thre current channel values whenever a channel is updated
- stream(stream_mode="updates") yields the update sent to each channel by each node
- this removes the __end__ value present at the end of each call to Graph/StateGraph/MessageGraph.stream(). To access the __end__ value either call .invoke() or stream(stream_mode="values")
