/**
 * Hook that resolves the effective layout direction for JS-driven logic
 * (e.g. gesture deltas) that Yoga logical props cannot cover.
 *
 * @description
 * Reads the direction provided via `HeroUINativeProvider` config (`isRTL`), or
 * the nearest `LayoutDirectionScope` override. Falls back to the global
 * `I18nManager.isRTL` state when no provider value is available, which matches
 * the default React Native behavior.
 *
 * @returns `true` when the layout direction is right-to-left
 *
 * @example
 * ```tsx
 * const isRTL = useIsRTL();
 * const translateX = isRTL ? -offset : offset;
 * ```
