Add kit system, KitManager and Goblin kit

Introduce a full kit framework and supporting utilities.

- Add core kit API: Kit, Playstyle, ActiveAbility, PassiveAbility, AbilityResult, charge state and PlayerChargeData.
- Implement KitManager for registration, lobby selections, apply/remove/clear lifecycle and charge tracking.
- Add KitEventDispatcher listener to centralize kit event handling (interact, hits, move) and integrate passive/active hooks.
- Provide example kit implementations: GoblinKit (functional abilities) and TemplateKit (reference).
- Add utilities: ItemBuilder and WorldEditUtils (WorldEdit-based sphere creation).
- Integrate into plugin: SpeedHG now initialises KitManager, registers kits and KitEventDispatcher, applies kits at game start and clears on end.
- LanguageManager: add default message/list/component helpers.
- Build changes: bump Kotlin plugin to 2.2.0 and add WorldEdit compileOnly deps; also expose legacySerializer in Extensions.

These changes implement the kit feature set (items, abilities, charge/recharge flow) and wire it into the game lifecycle.
