Pokemobs 1.8

Resolved a subtle permission bypass vulnerability in GriefPrevention-protected regions. The original implementation relied solely on allowBuild() permission checks, which in GriefPrevention's permission hierarchy only validates block placement privileges—not entity interaction rights. This meant players without claim trust could still capture protected mobs, despite GriefPrevention correctly blocking the projectile damage event (producing the "you can't harm that here" message).

The fix implements a comprehensive trust verification cascade: allowBuild() → allowContainers() → allowAccess(), ensuring capture attempts respect the full spectrum of GriefPrevention's permission model.
