ARC-SORT v0.1.1

• Output boxes: tracks now report the detection box they were matched to this frame
  (output_box="detection", new default). output_box="kalman" keeps the 0.1.0 behaviour (the
  Kalman-filtered state). Association is unchanged; HOTA rises in every setting tested, e.g.
  validation with the full pipeline: SportsMOT 84.957 → 86.295, DanceTrack 60.617 → 61.329.
  scripts/reproduce.sh keeps OUTPUT_BOX=kalman by default so arXiv:2610.22306 v1 still
  reproduces exactly; scripts/regression_gate.sh stays byte-identical on all three submissions.
• Motion-compensated trails: Visualizer(motion_compensated_trails=True) with the new
  ARCTracker.camera_motion property; tools/pipeline.py --motion-trails. Uses Roboflow
  trackers (now part of the optional viz extra).
• tools/run_cached.py --output-box; tools/evaluate.py --benchmark soccernet.
• README: comparison with Roboflow trackers 2.6.1 (SoccerNet test, SportsMOT/DanceTrack val with
  detections and GT boxes); tested-detectors table rerun with 0.1.1.
