VS killmkill97

Fixed an issue where the Button of Annihilation cluster bombs in Destruction Mode could trigger the damage-cap warning when hitting the lower part of the killmkill97 boss, due to the dedicated damage from the blue child projectiles overlapping with vanilla explosion damage.

• Only the terrain-destruction explosion damage is now excluded from killmkill97.

• The projectiles' actual combat damage and block destruction remain unchanged.

Fixed missing textures for Singularium Armor on Forge 1.20.1.

• Updated the armor material texture paths to match singularium_armor_layer_1/2.png.

Changed the Sword of Spacetime attack damage and execution damage to use Integer.MAX_VALUE.

• The tooltip now also displays Integer.MAX_VALUE.

• The killmkill97 boss's own Space Slash still uses the maximum Float damage value and remains unchanged.

Fixed horizontal and vertical flipping of the killmkill97 billboard texture on Forge 1.20.1.

• The UVs are now flipped directly instead of relying on camera rotation, ensuring the texture orientation is applied consistently.
