kiyo9w d38d863873 perf: bound OCR so a walking scan stays real-time, and add walk pacing
macOS Vision holds the GIL for the ~124 ms it takes to read a rail band, so the
tag pass decides the live frame rate: with 2 bands every 15 frames a walking
session fell to 1.7 results/s, and 1 band every 30 frames brings it back to 7.2
with tags still settling in a second or two. Measured, not guessed - the same
walk, same method (orb), only the OCR duty cycle changed.

The walk also gained a `pan` parameter (default 0.06, clamped 0.005-0.5) so a
demo can choose its pace: pan=0.02 sweeps a row over ~8 s, which reads like a
person rather than a time-lapse.

Demo configuration measured end to end on the walk (20 s, 1280x720, one client):
orb, pan=0.02, 1 band/30 frames -> 7.2 results/s, 178 labelled tracks, 21
distinct SKUs, first label 0.7 s, 3 readable price tags.
