Reduced false positives by relaxing printer detection thresholds, made single placement warnings non-blocking, improved command burst tolerance, and kept repeated suspicious behavior detectable for real offenders.

Fixed an error caused by graduated punishments directly kicking/banning players in ProtocolLib async packet listening.
Punishment actions are now properly scheduled to run on the main thread, compatible with Paper/Spigot async safety checks.

Enhanced EasyPlace Detection: Implemented precise modeling for EasyPlace patterns instead of simple hitVec range checks.
PlacementGuard Upgrade: Added fine-grained printer mode recognition with statistical correlation analysis between placement direction and player facing.
