/**
 * Build-your-own hook: stable references to shape edge-label primitives.
 *
 * Returns `edgeLabel` and `createShapeLabelPolicy` for consumers building
 * custom shape layers that need edge-label decorations and the annotation-opt-in
 * coupling described in ADR-0017, without reimplementing the placement logic.
 *
 * Named `useShapeLabelHelpers` to distinguish it from the existing
 * `useShapeDecorations` internal hook.
 *
 * @example
 * ```tsx
 * const { edgeLabel, createShapeLabelPolicy } = useShapeLabelHelpers();
 * const policy = useMemo(() => createShapeLabelPolicy({
 *   annotateWhen: (_f, ctx) => ctx.isViewportInsideShape,
 *   resolve: (_f, ctx) => ctx.isSelected ? "force" : "auto",
 * }), [createShapeLabelPolicy]);
 *
 * // Inside getDecorations:
 * getDecorations: (feature) => [edgeLabel(feature.properties?.name)],
 * ```
