PRUNplanner doesn't model travel, so nothing in the project could answer "how far is planet X" until now. Builds a graph from /systemstars (698 systems, real jump connections + 3D coordinates) and runs Dijkstra weighted by straight-line ly (what FTL fuel/time actually scale with), reporting jump count alongside.
