/**
 * Cycles through previous submissions with UP/DOWN arrow keys.
 *
 * State machine for navigation (3 phases):
 *
 *   idle    — no navigation active.
 *   primed  — first key press (UP/DOWN) consumed by native cursor movement.
 *   cycling — UP/DOWN keys walk through the history stack.
 *
 * Transitions on arrow key press:
 *
 *   idle  + empty input + UP    → cycling  (skip primed, start navigating immediately)
 *   idle  + empty input + DOWN  → idle     (nothing to cycle to)
 *   idle  + has text    + UP/DN → primed   (let native cursor move first)
 *   primed  + same direction    → cycling  (second press enters history)
 *   primed  + diff direction    → primed   (re-prime for the new direction)
 *   cycling + same direction    → cycling  (keep walking history)
 *   cycling + diff direction    → primed   (let native cursor adjust, re-prime)
 *
 * The composer calls reset() on any user edit and record() on submit, both of
 * which return the machine to idle.
