NBT Identification: Now uses PersistentDataContainer instead of item names. This prevents players from spoofing jetpacks by renaming normal armor in an anvil.
Durability System: Jetpacks now take damage based on fuel used. Controlled via the fuel-per-durability config (e.g., 1 damage per 5 fuel).
Repair Blocking: Added an anvil and grindstone interceptor. If unrepairable is true, players can only rename the item; they cannot fix it with materials or add enchants like Mending.
Auto-Sync Configs: New keys are automatically injected into config.yml and messages.yml on startup without overwriting existing custom settings.
Logic Optimization: Refined the BukkitRunnable and MoveEvent handling to ensure smooth flight visuals with lower impact on server TPS.
