+ * Validates that all groups in configuration are either predefined or custom.

+ * Ensures that every group specified in the configuration either:
+ *
+ * 1. Is a valid predefined group (combination of modifiers and selectors)
+ * 2. Is defined in customGroups
+ * 3. Is the special 'unknown' group.
+ *
+ * Also validates that there are no duplicate groups.
+ *
+ * @example
+ *
+ * ```ts
+ * // Valid predefined groups for React imports
+ * validateGeneratedGroupsConfiguration({
+ *   options: {
+ *     groups: ['react', 'external', 'internal', 'side-effect-import'],
+ *     customGroups: [],
+ *   },
+ *   selectors: ['import', 'export'],
+ *   modifiers: ['side-effect', 'type', 'value'],
+ * })
+ * // All groups are valid predefined groups
+ * ```
+ *
+ * @example
+ *
+ * ```ts
+ * // Invalid group that doesn't exist
+ * validateGeneratedGroupsConfiguration({
+ *   options: {
+ *     groups: ['my-special-group'], // Not predefined, not in customGroups
+ *     customGroups: [],
+ *   },
+ *   selectors: ['property', 'method'],
+ *   modifiers: ['static', 'private'],
+ * })
+ * // Throws: Error: Invalid group(s): my-special-group
+ * ```
+ *
+ * @example
+ *
+ * ```ts
+ * // Valid with custom groups for class members
+ * validateGeneratedGroupsConfiguration({
+ *   options: {
+ *     groups: ['static-property', 'constructor', 'lifecycle-methods'],
+ *     customGroups: [

+ *         groupName: 'lifecycle-methods',
+ *         elementNamePattern: [
+ *           /^componentDidMount$/,
+ *           /^componentWillUnmount$/,

+ *       },
+ *     ],
+ *   },
+ *   selectors: ['property', 'method', 'constructor'],
+ *   modifiers: ['static', 'private', 'public'],
+ * })
+ * // 'static-property' is predefined, 'lifecycle-methods' is custom
+ * ```
+ *
+ * @param params - Configuration parameters to validate.
+ * @throws {Error} If any group is neither predefined nor custom.
