Create model to run and union our weighted dependency graphs

[ccerv1]

What is it?

First, we need some intermediate model or generic way of constructing the event graph.
Then we should be able to call our new openrank.py and run at least two different weighting algorithms.
Finally, we need to union the results into a new model, eg, int_weighted_dependency_graph

• onchain_builder_project_id
• dev_tooling_project_id
• edge_type
• edge_weight
• weighting_algorithm
• created_at

Probably best to have this in a single SQLMesh Python model that can be executed on demand.
