Dynamic Siege Mechanics: Ravager Breaching and Illager Engineers

Raids are currently too easy to cheese with simple walls. I propose: ​Breaching Ravagers: During raids, Ravagers can break low-resistance blocks (wood, dirt, stone, cobblestone) when charging. This is active ONLY during raids. ​Illager Engineers: New units that carry materials to bridge moats or place ladders to scale walls. ​Scaling Difficulty: These mechanics activate after 2 successful village defenses. On Hard difficulty, they start from Wave 1. ​This makes village defense a strategic priority for players!
