因为我不懂C，在AI的指导下一番调试之后，它给出了诊断：
输出表明，BuildSyllableGraph 在图构建阶段完全没有生成任何边，顶点只有起点 0。这很可能是因为在 UCRT64 环境下，SpellingAccessor 在 spelling_map_ 为空时的行为与测试预期不符，导致拼写插入失败。
原始测试中 Build(keyset) 没传 script，导致 prism 内部 spelling_map_ 保持为 nullptr。虽然 SpellingAccessor 对 null 有降级处理（直接返回 spelling_id 作为音节），但在 UCRT64 编译环境下，可能因为结构对齐、优化或未定义行为导致 while (!accessor.exhausted()) 循环内的插入逻辑异常，最终 spellings 被判为空，边被丢弃。
