Fixed

• Critical Lifecycle Issues: Fixed memory leaks and stale references during plugin reloads
  • Static instance now properly nullified on disable
  • Explicit event listener unregistration to prevent duplicate events
  • Added null-safe checks in onDisable to prevent crashes
• State Persistence Improvements:
  • Changed worldStatesCache to ConcurrentHashMap for thread safety
  • Fixed PlaceholderAPI stale references by changing persist() to false
  • Re-checks PAPI availability on every reload/enable
• Code Quality:
  • Removed unused imports and fields
  • Updated versioning for consistency
