Fixes

• Populated FleaPriceRoubles, HandbookPriceRoubles, HandbookParentId field mappings during NewItem object initialization (#9)
• Fixed validation logic defects for HandbookParentId in CreateItemFromClone and CreateNewItem, removed incorrect required checks (#10, #11, #12)
• Fixed redundant parameter issue in AddItemToAssort method calls

Refactoring & Optimization

• Removed legacy AbstractNewItem abstract base class and its subclasses (NewItemCommon, NewItemAmmo, NewItemDrinkOrFood, NewItemMedical)
• Unified NewItem architecture: All item types now share the NewItem class, with property application determined by the assigned AbstractInfo instance
• Marked AmmoInfo class as [Obsolete], planned for refactoring in a future version
• Marked BaseInfo.IsHadInit property as [Obsolete], to be removed after version 0.2.0
• Added NewItemExtensions extension class, implementing ToStringWithStatus() and ToIdNameString() methods for unified log formatting output
• Removed unused dependency injections (ISptLogger, DatabaseService) from DataLoader constructor
• Added [UsedImplicitly] attribute to INewItem.PropertyOverride property to eliminate warnings

Data Format Changes

• Removed the $type field from item templates (backward compatible reading retained)
• Type mechanism clarification: Item properties are determined by the actually assigned Info fields, independent of baseInfo.type
• Data files now support JSONC comments (single-line // and multi-line /* */), added StripJsoncComments method to DataLoader with state machine parsing logic

New Features

• Support for Chinese rarity keys (Common, Rare, Super Rare, Nonexistent)
• Support for Chinese item sound keys
• Support for ammunition type item validation

Configuration Updates

• Added cacheInitialized configuration option to control cache initialization skipping and state persistence
• Added alwaysUpdateCache configuration option to force cache updates
• Added requiredItemIds configuration option to validate existence and enabled status of required items
• See Mod Configuration documentation for details

Validation System

• Built a unified validator system, implementing IValidator interface and chaining calls
• Added BaseInfoValidator: validates required fields, MongoId format, type validity
• Added AttributeInfoValidator: validates positive integer dimensions, rarity, sound type
• Added BuffsInfoValidator: validates Buff effect configurations
• Added MedicalInfoValidator, DrinkFoodInfoValidator, AmmoInfoValidator: respectively validate medical, food/drink, and ammunition configuration logic
• Removed invalid negative weight validation logic
• Enhanced error collector to carry item path information for easier problem localization

Architecture Optimization

• Changed UpdateProperties and UpdateDatabaseService methods to protected, restricting external calls
• Enhanced null validation logic for BaseInfo and BuffsInfo
• Improved deserialization error logging, added complete exception stack traces

修复问题

• 补全 NewItem 对象初始化时的 FleaPriceRoubles、HandbookPriceRoubles、HandbookParentId 字段映射 (#9)
• 修正 CreateItemFromClone 和 CreateNewItem 中的 HandbookParentId 验证逻辑缺陷，移除错误的必填检查 (#10, #11, #12)
• 修正 AddItemToAssort 方法调用中冗余参数的问题

重构优化

• 移除旧版 AbstractNewItem 抽象基类及其子类实现（NewItemCommon, NewItemAmmo, NewItemDrinkOrFood, NewItemMedical）
• 统一 NewItem 架构：所有物品类型共用 NewItem 类，通过已赋值的 AbstractInfo 实例决定属性应用
• 标记 AmmoInfo 类为 [Obsolete]，计划后续版本重构
• 标记 BaseInfo.IsHadInit 属性为 [Obsolete]，将在 0.2.0 版本后移除
• 新增 NewItemExtensions 扩展类，实现 ToStringWithStatus() 和 ToIdNameString() 方法，统一日志格式化输出
• 清理 DataLoader 构造函数中未使用的依赖注入（ISptLogger、DatabaseService）
• INewItem.PropertyOverride 属性添加 [UsedImplicitly] 特性以消除警告

数据格式变更

• 移除物品模板中的 $type 字段（保留向后兼容读取）
• 类型机制澄清：物品属性由实际赋值的 Info 字段决定，与 baseInfo.type 无关
• 数据文件现支持 JSONC 注释（单行 // 和多行 /* */），DataLoader 增加 StripJsoncComments 方法及状态机解析逻辑

新功能

• 支持中文稀有度键（普通、稀有、超级稀有、不存在）
• 支持中文物品音效键
• 支持弹药类型物品验证

配置更新

• 新增 cacheInitialized 配置项，控制缓存初始化跳过及状态持久化
• 新增 alwaysUpdateCache 配置项，强制更新缓存
• 新增 requiredItemIds 配置项，验证必需物品存在性与启用状态
• 详见模组配置文档

验证系统

• 构建统一验证器系统，实现 IValidator 接口与链式调用
• 新增 BaseInfoValidator：验证必需字段、MongoId 格式、类型合法性
• 新增 AttributeInfoValidator：验证尺寸正整数、稀有度、音效类型
• 新增 BuffsInfoValidator：验证 Buff 效果配置
• 新增 MedicalInfoValidator、DrinkFoodInfoValidator、AmmoInfoValidator：分别验证医疗、饮食及弹药配置逻辑
• 移除无效的负数重量校验逻辑
• 增强错误收集器，支持携带物品路径信息以便定位问题

架构优化

• 将 UpdateProperties 和 UpdateDatabaseService 方法改为 protected，限制外部调用
• 增强 BaseInfo 和 BuffsInfo 的空值校验逻辑
• 改进反序列化错误日志，添加完整异常堆栈信息
