/**
 * Deep-merges `source` into `target` in-place.
 * Uses the same merge semantics as {@link ConfigProto}:
 * - Nested plain objects are merged recursively
 * - {@link isAtom | Atomic} values replace the target entirely
 * - Everything else (primitives, arrays, class instances) replaces the target value
 *
 * Designed for patching `Config.defaultOptions` without losing existing keys:
 *
 * ```js
 * Jodit.configure({
 *   controls: {
 *     someButton: { group: 'custom' }
 *   }
 * });
 * // Only `controls.someButton` is touched — all other controls remain intact.
 * ```
 *
 * @see {@link ConfigProto} for the prototype-chain variant used at editor creation time
