Choosing MST on the research map built and sorted every pair of pins (~2.2 million edges for the
2,107-pin roster), ~12 s on the main thread, and then did it all again for a log line. The page froze,
and check:clustering-modes read the map before any line existed: "MST drew no cluster lines".
- MSTClusteringUtil runs Prim over the implicit complete graph: O(n²) time, O(n) memory, no edge list.
Starting a new tree when the nearest outside point is beyond maxConnectionDistance gives the same
spanning forest as before.
- useMapClustering no longer recomputes every tree for its stats log line.
- check:mst-clustering (headless, in gates:post): same edge count and total length as a reference
all-pairs Kruskal on 2-400 pins, capped and uncapped; 2,107 pins in 872 ms here (budget 3 s).
On the previous code it FAILs at 11,206 ms.
