Swipe navigation felt sluggish next to native tvOS apps: Plezy priced a
focus step at 0.55x the focused item's extent, throttled repeats to 140ms,
and stopped dead on finger lift - the inverse of the native engine's feel.
Retuned AppleTvRemoteTouchService to on-device measurements of the native
focus engine (issue #2006):
- one focus step per fixed 400pt of touch travel; drop item-extent scaling
(measured step distance was identical across a 230pt and a 345pt axis)
- repeat cadence 140ms -> 60ms (native median)
- fast lifts glide one or two extra steps (>=2000 / >=8000 pt/s) within
~130ms of the lift; reversal pivots and new touches cancel the glide
