feat: 实现游戏核心系统和UI组件

核心系统:
- combatSystem: 战斗逻辑、伤害计算、战斗状态管理
- skillSystem: 技能系统、技能解锁、经验值、里程碑
- taskSystem: 任务系统、任务类型、任务执行和完成
- eventSystem: 事件系统、随机事件处理
- environmentSystem: 环境系统、时间流逝、区域效果
- levelingSystem: 升级系统、属性成长
- soundSystem: 音效系统

配置文件:
- enemies: 敌人配置、掉落表
- events: 事件配置、事件效果
- items: 物品配置、装备属性
- locations: 地点配置、探索事件
- skills: 技能配置、技能树

UI组件:
- CraftingDrawer: 制造界面
- InventoryDrawer: 背包界面
- 其他UI优化和动画
