Matt 3fd07eea91 fix(offroute): smooth max_grade penalty instead of hard cliff (DEM noise robustness) ... A single noisy DEM cell could fabricate a huge fake slope and make an edge unconditionally impassable, forcing the pathfinder to route around passable terrain. Replace the hard cliff (|grade|>max_grade -> skip) with a smooth exponential penalty: no penalty up to max_grade, then base_time *= exp(overshoot * SLOPE_PENALTY_SCALE); only grades whose penalty exceeds SLOPE_PENALTY_CAP (true bad data / vertical) are dropped. Routing can now see through noisy cells while still strongly avoiding real cliffs. Penalty only raises edge cost, so the heuristic stays admissible. 2 tests: smooth penalty traverses a >max_grade gap (finite, raised cost) yet routes around / drops a past-cap grade; exactly-at-threshold grade incurs no penalty.
