 - Resolves the native mappin system when one of those paths fires, logs relevant

+Active build note:

+- The currently installed build is read-only. It disables provider class
+  multiplier overrides and enables local GPS search tracing.
+- It hooks `GPSSearch` (`0x44f054`), `GPSRouteProducer` (`0x44cc7c`),
+  `GPSEdgeCost` (`0x44f838`), and the two cost-provider filters
+  `0x44ff68`/`0x450b08`.
+- The filter probe records pass/fail counts by point class and by the
+  `point + 0x10` mask bits tested against provider masks at `+0x108`/`+0x10a`.
+  This is meant to identify whether class/mask filtering, rather than the edge
+  multiplier table, is dominating route choice.

 Current route-probe focus:
