Replace threshold-based swipe with live drag-follow in article view

The article now visually tracks the finger in real time while swiping
(via a rAF-throttled touchmove handler), instead of only reacting
after the fact on touchend. On release it completes the page-turn if
dragged past ~35% of the article's width, or on a fast-enough flick
even short of that distance; otherwise it springs back to center.
Dragging past the first/last article is damped rather than free, for
tactile feedback that there's nothing further that way. A vertical
drag is detected within the first ~10px of movement and left alone so
it can't fight normal page scrolling.

Also fixes a real bug found while testing the flick path: Date.now()
has ~1ms resolution, so a genuinely fast flick often measures as
elapsed === 0. The velocity calculation was treating that as "zero
velocity" (dividing 0 elapsed into "no flick") instead of "as fast as
it gets" — now a zero-elapsed gesture with real movement counts as a
flick outright.
