Contributions summary:Kamil primarily introduced and modified code related to the "factory-kit" design pattern, a creational pattern used for creating objects. They implemented new weapon types (Sword, Axe, Bow, Spear) and the core logic for the factory, including the `WeaponFactory` interface and the `Builder` interface. Their work involved modifying existing test classes to accommodate and verify the functionality of the factory-kit implementation and the introduction of the factory-kit pattern.
