- DecodingCache 提供 withSnapshot 高阶函数，集中管理快照的创建、压栈和出栈
- 使用 defer 确保正常返回与异常抛错均能正确清理当前作用域快照
- 出栈时增加引用相等性校验（===），防止栈错位误删外层快照
- snapshots 属性收窄为 private(set)，Cachable 协议仅暴露只读 { get }，防止外部随意篡改
- JSONDecoderImpl+Unwrap 中全面接入 withSnapshot，并新增 decodeInPlace 供就地解码复用
- SmartFlat 解码时通过 decodeInPlace 为内层模型建立快照作用域，消除快照残留与后续属性污染 - SmartAny 模型兜底解码路径同样接入 decodeInPlace，保持模型声明默认值 - SmartIgnored 在无 parsingMark 路径下修正 codingPath 层级，准确获取宿主声明的初始值
- 新增 DecodingCacheLifecycleTests：覆盖正常返回、抛错恢复、类型过滤、嵌套作用域、平铺栈深度、字典直接解包及无 mark SmartIgnored 等契约断言 - 新增 SmartFlatTests：覆盖 @smartflat 后的普通属性默认值、枚举默认值、SmartIgnored、SmartAny、数组元素、以及 mappingForValue 转换器等防污染场景
- 更新 CONTRIBUTING.md 中的 DecodingCache 约定为 withSnapshot 作用域接口 - 更新 TechnicalGuide.md 中的解码流程架构图与快照作用域机制 - 更新 QA3.md 中的示例代码与快照原理示意
- 新增 DecodingSnapshot（模型上下文，objectType 不可变，懒加载默认值与转换器） 与 PropertyDecodingContext（宿主属性边）；JSONDecoderImpl 携带固定上下文成员， unwrap/decodeInPlace 经 decoderForEntry 为每次可观察模型入口新建上下文 - KeyedContainer 创建时固定绑定所属模型；默认值、Key Mapping、transformer 均读自身 snapshot，不再查询活动 owner 栈 - 数组元素、字典数据键、nestedContainer/superDecoder 原始结构清空属性边； 普通 Codable 子对象不继承宿主字段表 - SmartIgnored/SmartHexColor 经属性边恢复完整包装器声明； SmartAssociatedEnumerable/SmartAny 经属性边取当前属性 transformer - 删除 DecodingCache、双栈、scopeIdentifier、activeOwner 与跨路径查找 - 修正 transformer 路径 didFinishMapping 双重通知（计数测试证明 2→1） - 测试迁移：DecodingCacheLifecycleTests → DecodingContextTests 语义契约； 新增 RefactorPlanRegressionTests（R01/R02 等）；CI 增加 Release 与触发分支

Set explicit read-only GITHUB_TOKEN permissions for the workflow.
The workflow has no permissions: block, so token access follows the repository or organization default. Neither job needs write access. Set contents: read and disable credential persistence on both checkout steps.

改动说明 / Summary
将解码上下文改为按模型解码入口独立创建，并让容器固定绑定所属模型，避免嵌套模型、
@SmartFlat、数组及属性包装器之间的默认值、字段映射和包装器配置相互串扰。修复
SmartIgnored的编码状态保留问题，并新增decodeWrappedValue(from:)，供需要切换到内层 SmartCodable 模型上下文的自定义包装器使用。同时补充解码回归测试、技术文档和 Thread Sanitizer CI 覆盖。改动类型 / Type
关联 Issue / Related Issue
Closes #
验证方式 / How to Test
swift build通过GitHub Actions 在提交
9b286ad上的 Debug/Release 构建与测试、两项 Thread Sanitizer 检查均通过：查看 CI 运行。注意事项 / Notes
未发现破坏性变更。新增的
decodeWrappedValue(from:)是面向自定义包装器的公开辅助接口；同时遵循PropertyWrapperable与SmartDecodable的包装器，可按需用它让内层模型使用自己的解码上下文。Summary by CodeRabbit
SmartIgnoredproperties now retain their encoding settings after model mapping completes.
