🔲 Island Border — See Your Boundaries

Adds a visible world border around each player's island. Players can see exactly where their island ends, preventing accidental wandering and protecting neighboring islands.

Features

• Configurable appearance — wall style, particles, or vanilla world border effect
• Per-island sizing — borders match each island's actual protection range
• Performance friendly — minimal server impact
• Works with all BentoBox game modes
