 * Deep transform an object using a transformer specification

 *   - object values: recursively applied to nested objects
 *   - other values: used directly as the new value
 * @returns New transformed object (original is not mutated)
 *
 * @example
 * const obj = { name: 'hero', count: 5 };

 *   name: (v) => v.toUpperCase(),
 *   count: (v) => v * 2,
 * });

 * @example
 * // Nested transformation
 * const obj = { schema: { title: 'old' } };
 * const result = deepTransform(obj, {
 *   schema: { title: 'new' }
 * });
 * // result: { schema: { title: 'new' } }
