 * Returns: [esm-root, essentials-root]
 *
 * This ensures the direct preset's binaries have highest PATH priority,
 * allowing more specific presets to override base preset binaries.
 * @param node the root preset node to traverse
 * @returns array of unique preset root paths, closest to consumer first
