Refactor kits, add safety checks and fixes

Multiple refactors and defensive fixes across kits and event handling:

- RecraftManager: use Bukkit.getOnlinePlayers() collection API instead of stream.
- ActiveAbility: mark backing _hitsRequired as @Volatile for thread-safety.
- BlackPanther, Rattlesnake, TheWorld, Gladiator, Goblin, Venom, Voodoo: change how kit overrides are accessed (lazy or helper) to avoid stale initialization and improve readability.
- Gladiator: add an ended flag to avoid double-ending fights.
- Goblin & TheWorld: add game state checks to avoid restoring kits or operating on players after game end.
- Rattlesnake: guard scheduled miss task with player.isOnline check and simplify action bar call.
- Venom: clean up active shield tasks on kit removal and make damage handling null-safe with apply.
- Voodoo: wrap passive tick in runCatching and log failures to prevent uncaught exceptions from killing tasks.
- KitEventDispatcher: skip handling if victim is not alive, change interact handler to ignoreCancelled = false, and add isAlive helper.
- ItemBuilder: switch lore serialization to MiniMessage, disable default italic decoration, and reuse a MiniMessage instance.

These changes improve robustness, avoid race conditions, and add defensive guards against invalid state during scheduled tasks and event handling.
