 * @brief Test XnodeAgent objects using REAL production encode/decode functions from mndXnode.c
 * @version 1.0
 * @date 2025-12-25
 *
 * This test uses actual production encode/decode functions by linking against mnode library.
 * Tests cover all four XnodeAgent object types with real SDB operations.
