+ * Cleans and normalizes the groups configuration in options.
+ *
+ * Performs the following optimizations on the groups array:
+ *
+ * - Removes empty arrays (they serve no purpose in grouping)
+ * - Converts single-element arrays to plain strings (simplifies structure)
+ * - Preserves multi-element arrays as-is (maintains subgroups).
+ *
+ * This normalization ensures consistent group handling and eliminates
+ * unnecessary complexity in the configuration.
+ *
+ * @example
+ *
+ * ```ts
+ * getOptionsWithCleanGroups({
+ *   groups: [
+ *     'imports',
+ *     ['types'], // Single element - will become 'types'
+ *     ['hooks', 'utils'], // Multiple elements - preserved as array
+ *     [], // Empty - will be removed
+ *     'components',
+ *   ],
+ * })
+ * // Returns: {
+ * //   groups: [
+ * //     'imports',
+ * //     'types',
+ * //     ['hooks', 'utils'],
+ * //     'components'
+ * //   ]
+ * // }
+ * ```
+ *
+ * @template CustomTypeOption - Custom type option string for GroupsOptions.
+ * @template Options - Type of options extending
+ *   GetOptionsWithCleanGroupsParameters.
+ * @param options - Options object containing groups to clean.
+ * @returns Options with cleaned and normalized groups array.
