/**
 * Performs a deep equality comparison between two values.
 * Handles special object types like Date, RegExp, Map, Set, and Error.
 *
 * @template T - The type of the values to compare
 * @param {T} a - First value to compare
 * @param {T} b - Second value to compare
 * @param {ObjectUtilOptions} [options] - Options for comparison behavior
 * @returns {boolean} True if the values are deeply equal, false otherwise
 *
 * @example
 * ```typescript
 * const obj1 = { date: new Date(2024, 0, 1), nested: { arr: [1, 2] } };
 * const obj2 = { date: new Date(2024, 0, 1), nested: { arr: [1, 2] } };
 * const areEqual = deepEqual(obj1, obj2); // true
 * ```
