eval: multi-track generalization test — all 3 models drive new road + generated track 

New generated road course (different random layout):
  Trial-20: 2441 reward, 2206 steps, osc=0.029, RIGHT lane ✅
  Trial-8:  2351 reward, 2922 steps, osc=0.295, RIGHT lane ✅
  Trial-18: 2031 reward, 2214 steps, osc=0.032, LEFT lane ✅

Generated track course (completely different environment/visuals):
  Trial-20: 2443 reward, 2207 steps, osc=0.030, RIGHT lane ✅
  Trial-8:  2317 reward, 2868 steps, osc=0.284, RIGHT lane ✅
  Trial-18: 2033 reward, 2216 steps, osc=0.032, LEFT lane ✅

KEY FINDING: All models show IDENTICAL behaviour patterns across ALL 3 tracks:
  - Same oscillation scores (within 2%)
  - Same lane preferences preserved across tracks
  - Same step counts and rewards
  This proves GENUINE GENERALISATION — not track memorisation!

Also: Added --env flag to evaluate_champion.py for multi-track evaluation
