Builders Wand Ultimate v1.1.3

Changelog:
## Bug Fixes

- Fixed server log spam caused by an IllegalArgumentException when a player aimed their wand at a wall sign,
wall banner, wall torch, or similar block-only materials that have no item form (e.g. OAK_WALL_SIGN). The wand will
now correctly skip counting these materials without throwing an error.
- Fixed deprecated Sound.valueOf usage that could produce warnings on newer Paper builds.

## Internal

- Refactored WandEvents into separate handler classes (BuildingHandler, SelectionHandler, ParticleHandler,
StorageHandler) for improved maintainability. No behaviour changes.

When stacking, it would not respect even surfaces

Fixed rate limiting when using wand

Critical Security Fixes

• Fixed Economy Exploits - Prevented race conditions in wand upgrade transactions that could cause money duplication
• Storage Bypass Protection - Blocked rapid-clicking exploits that allowed bypassing blacklist/whitelist restrictions
• NBT Security Hardening - Added comprehensive validation to prevent malicious NBT injection attacks
• Transaction Atomicity - Wand upgrades now validate completely before withdrawing money, preventing loss on failures

Performance Improvements

• Memory Leak Prevention - Added automatic cleanup on player disconnect and periodic maintenance
• Thread Safety - Replaced HashMaps with ConcurrentHashMaps throughout for better multi-threading
• Particle Optimization - Implemented distance-based rendering (64 block limit) and proper fallback mapping
• Rate Limiting - Added cooldowns for storage interactions to prevent server lag from spam-clicking

Bug Fixes

• Particle Mapping - Fixed sculk shriek and other particles displaying as flame instead of correct type
• Storage Validation - Enhanced pre-validation system with dual-layer security checks
• Event Priority - Resolved timing conflicts between storage validation and other plugin interactions
• State Management - Improved cleanup of upgrade states and tracking data

Technical Improvements

• Compilation Fixes - Resolved lambda expression and method signature issues
• Error Handling - Better logging and debugging for storage and economy operations
• Code Organization - Added ParticleMapper and NBTValidator utilities for cleaner architecture
• Configuration - Enhanced debug options for troubleshooting storage and economy issues

Compatibility Notes

• Maintains full backward compatibility with existing configurations
• No database migrations required
• All existing wands and player data preserved

Recommended Action: Update immediately for security improvements. No configuration changes needed.
