PermaEfe Extreme Survival

The update for Minecraft 1.21.6 introduces the migration of the interactive book system to trigger commands, eliminating the elevated permissions warning screens. The totem failure logic was rewritten using void damage to bypass the base game's invulnerability frames, and Ghast behavior was optimized by implementing the new flying speed attribute. NBT selector and particle syntax were also corrected to comply with the strict coding rules of this version.
