This refinement keeps a single connected edge for each point: the one with the lowest score based on connected 🝰 Heuristics.
Note that the remaining Edge can be the same for multiple, different Vtx.
Not all heuristics can be yield usable scores outside of a search context. For example, 🝰 Azimuth and 🝰 Inertia require clear seed/goals and search history to assign a given score. Such heuristics will yield a default score based on their own settings.
