decimal_checked API

DecimalChecked 是封闭的 IEEE 十进制流水线，保存一个不可变 DecimalContext、当前定义 Decimal、本步 flags 与全流程累计 flags。

构造与观察

parse 和 from_* 构造器会先强制 context 使用 IEEE profile。 value、context、raised 与 flags 分别观察状态；outcome 返回值与累计 flags。clear_flags 开始新的观察窗口，但不改变值或 context。

Contextual 运算

每个算术方法委托给 decimal 对应 contextual 运算并组合 flags。二元方法接收普通 Decimal，不会隐式合并两个独立的 context 与 flag 历史。IEEE NaN 与 infinity 仍是定义结果，不会被改写成 ArithmeticError。

完整公开接口

以下快照是 0.7.1 的完整生成包接口。
