ball_float_checked API

BallFloatResult 包装 Result[BallFloat, ArithmeticError]，同时保留区间语义。

构造与观察

ok、err、from_result、result 连接原始结果；exact、from_bounds、whole 及各类 from_* 构造包装区间。非法边界返回 Err。

组合与算术

map、bind、flat_map 会短路已有错误。绝对值、取负、四则运算、整数幂、规范化与精度调整均返回 Self，并实现标准运算符。

除数区间含零时会按 BallFloat 语义返回 whole-real enclosure，不会转成 Err。

完整数值接口包括 from_int、from_coefficient、from_float、from_double、 abs、neg、add、sub、mul、div、pow_nat、pow_int、 normalized 和 with_precision。

from_coefficient 接受 @bin_float.BinCoeff 与独立的 negative? 符号；二进制 checked API 不接受 BigInt。

完整公开接口

以下快照是 0.7.1 的完整生成包接口。公开声明是名称与签名的权威清单；前文按行为解释这些能力。
