Key Additions:

Additions in onlyDropIfNotSafe Method:

• The method is modified to include a configuration check for preserving items on death and applying item damage.
• Introduced a new check that applies damage to items if the itemdamage configuration is enabled.

Configuration Class:

• Added a new ItemDamage configuration class with several customizable options for item damage mechanics upon death.

Item Damage Logic:
Introduced a new ItemDamage class that contains the logic for applying damage to items when a player dies. The class ItemDamage implements the logic for applying damage to items upon player death. The logic includes:

• Checking if the item is damageable.
• Determining if the item will take damage based on a percentage chance.
• Applying randomization to the damage percentage if enabled.
• Calculating the new damage value and ensuring it doesn't exceed specified thresholds.
• Removing the item from the player's inventory if it is completely destroyed (if minimumItemHealth = 0)

Configurable Options

1. enabled: Whether item damage on death is enabled.
2. percentage: The likelihood that an item will take damage upon death.
3. baseDamagePercentage: The base percentage of damage an item should always receive upon death.
4. minimumItemHealth: The minimum damage value to be maintained for a player's items upon death.
5. percentageRandomness: Whether randomness in the damage percentage is enabled.
6. randomizedPercentageMin: The minimum damage percentage when randomness is enabled.
7. randomizedPercentageMax: The maximum damage percentage when randomness is enabled.
