Matt 3293cb4238 feat(offroute): Phase O3a — trail burn-in, pathfinder seeks trail corridors 
Trail friction REPLACES land cover friction where trails exist:
- Road (value 5): 0.1× friction
- Track (value 15): 0.3× friction
- Foot trail (value 25): 0.5× friction

TrailReader loads /mnt/nav/worldcover/trails.tif rasterized from OSM highways.

Validation shows trail-seeking behavior:
- On-trail travel: 17.3% → 98.7%
- Effort time: 1047 min → 155 min (-85.2%)
- Path travels farther but stays on roads for speed
