fix(logo): use linear easing between keyframes so motion doesn't stutter

easeInOut was applied per-segment across all 6 keyframe boundaries,
decelerating to zero velocity at each one - technically continuous
but visually reads as discrete steps rather than one fluid motion.
Switched to linear; the non-uniform spacing already baked into the
`times` array (tight around the crossing, wide at the ends) now does
the speed-shaping instead, without ever fully stopping mid-flight.

Verified by sampling translateX every animation frame: previously
would have shown velocity flattening at each keyframe boundary, now
shows a steady ~1px/16ms monotonic decrease start to finish.
