 * Deep structural equality for plain objects, arrays, and primitives. Keys
 * explicitly set to `undefined` are treated as absent (matching JSON
 * semantics), leaf values are compared with `Object.is`, and non-plain
 * objects (class instances, Maps, Sets, etc.) are only equal by reference.
 *
 * @example
 * ```ts
 * deepEqual({ a: [1, { b: 2 }] }, { a: [1, { b: 2 }] }); // true
 * deepEqual({ a: 1, b: undefined }, { a: 1 }); // true
 * ```
