+/**
+ * Merges configuration options with settings and defaults in priority order.
+ *
+ * Combines three levels of configuration with increasing priority:
+ *
+ * 1. Default values (lowest priority)
+ * 2. Global settings from ESLint configuration.
+ * 3. Rule-specific options (highest priority).
+ *
+ * This ensures that user-provided options always override settings, and
+ * settings always override defaults.
+ *
+ * @example
+ *
+ * ```ts
+ * const finalOptions = complete(
+ *   { type: 'natural' }, // User options (highest priority)
+ *   { order: 'asc' }, // Global settings
+ *   { type: 'alphabetical', order: 'desc' }, // Defaults (lowest priority)
+ * )
+ * // Returns: { type: 'natural', order: 'asc' }
+ * ```
+ *
+ * @template T - Type of the configuration object.
+ * @param options - Rule-specific options provided by the user (highest
+ *   priority).
+ * @param settings - Global settings from ESLint configuration.
+ * @param defaults - Default values for the configuration (lowest priority).
+ * @returns Merged configuration object with all three levels combined.
