 * Deeply merges multiple objects together, with configurable behavior for arrays and other options.

 * @template T - The type of the target object
 * @template U - The type of the source objects
 * @param {T} target - The target object to merge into
 * @param {...U[]} sources - The source objects to merge from
 * @param {MergeOptions} [options] - Options for merge behavior
 * @returns {T & U} The merged object
 *
 * @example
 * ```typescript
 * const target = { a: 1, b: { x: 1 } };
 * const source = { b: { y: 2 }, c: 3 };
 * const merged = mergeObjects(target, source);
 * // { a: 1, b: { x: 1, y: 2 }, c: 3 }
