Better Turtle Scute

1. Bug Fix​

• Issue: The passive effect of the Turtle Back Shell would not trigger again after the first activation, even when the cooldown period had expired.​
• Affected Version: Fabric 1.21.8​
• Resolution: Fixed the logic issue causing the passive effect to fail retriggering post-cooldown; the effect now activates normally according to the set cooldown rules.​

2. Feature Adjustment​

• Buff Addition: After the passive effect of the Turtle Back Shell is triggered, the player will now gain an additional 4 temporary hearts (as Damage Absorption).​
• Balance Adjustment: For balance purposes, the player will also receive a 120-second Unlucky effect simultaneously when the above passive effect is activated.
