 * Builds a tap gesture that hit-tests a chart's reference-line **badges** (the
 * pill tags for working orders / alerts / targets) and fires `onPress(line,
 * index)` when one is tapped. Mirrors {@link useMarkers}: badge rects are
 * projected to screen each frame on the UI thread (so they track the rescaling
 * axis exactly like the rendered pills), and the gesture hit-tests against them.
 *
 * Also returns a `hitTest` worklet so a coexisting gesture (the scrub-action tap)
 * can defer to a badge under the finger instead of acting on it. Only badge-tagged
 * Form-A (value) lines are pressable; everything else projects to `null`.
