按内容语义压缩工具结果：13 个 reducer 在 tools/post-execute 阶段按含义裁剪超长输出（保留失败的测试、丢弃 diff 上下文、对 JSON 与 CSV 抽样、lint 问题按规则归类、依赖库的调用栈帧折叠、文件过多的目录只给计数），完整原文落盘保存并留一个定位符可取回。

Content-aware tool-result reducer: 13 reducers cut oversized output by meaning at tools/post-execute (failing tests kept, diff context dropped, JSON and CSV sampled, lint problems grouped by rule, dependency stack frames collapsed, crowded directories counted), with full originals spilled to disk behind a locator.
