New Feature: Strict NBT Interceptor
This update introduces a new packet-level protection system to enhance server security against malicious or oversized NBT and custom payloads. Key functionalities include:

1. Player-Specific Alert System
   
   • Tracks each player’s suspicious packet activity.
     
     
   • First offense triggers a warning; second offense results in an automatic kick.
     
2. Custom Payload Monitoring (CUSTOM_PAYLOAD)
   
   • Inspects incoming custom payload packets for suspicious channels (e.g., containing nbt, payload, or book).
     
     
   • Checks payload size against a configurable maximum limit (default: 4096 bytes).
     
     
   • Cancels oversized or suspicious packets and alerts the player.
     
3. Creative Slot NBT Protection (SET_CREATIVE_SLOT)
   
   • Monitors items placed in creative mode slots.
     
     
   • Checks NBT data size against a maximum threshold (default: 1024 bytes).
     
     
   • Cancels packets with oversized NBT data and alerts/kicks the player accordingly.
     
4. Automatic Enforcement
   
   • Suspicious packets are automatically cancelled to prevent exploits.
     
     
   • Players exceeding thresholds are kicked to protect server integrity.
     
5. Failsafe Mechanism
   
   • Any unexpected errors in packet processing result in immediate packet cancellation and player kick to prevent potential exploitation.
