新增: Phase2 阶段收尾（Sprint 1-20）
重构：删 5 零引用 crate（df-evolve/plugin/stages/task/traceability）+ 清死模块、ai.rs 拆 11 子 module、ai.ts 拆 6 composable、i18n 拆目录 功能：知识库全栈（df-project/scan + CRUD + 时间线 + 前端）、Settings 拆分、appSettings KV 迁移、模型池、LLM 并发 Semaphore 修复：审批持久化根治、ConditionEngine 默认拒绝、NodeRegistry unimplemented 清除、promote 补偿删除、工具结果截断 50KB、路径校验防 symlink 逃逸 文档：B-03 人工审批设计、决策记录三分档、规格契约自检、经验记录、todo 看板、PROGRESS 更新 详见 PROGRESS.md。src-tauri/儿童每日打卡应用/ 与本项目无关，已排除。

//! 项目技术栈探测 — 浅读根目录标志文件识别技术栈
|
||||
//!
|
||||
//! 纯函数、零状态、零外部依赖(仅 std + serde_json + anyhow)。
|
||||
//! 只读根目录标志文件,不递归遍历(控制性能与安全)。
|
||||
//!
|
||||
//! 供 commands 层薄封装暴露为 IPC 命令,新建/导入项目时自动填充 `ProjectRecord.stack`;
|
||||
//! 未来 df-ai/df-workflow 亦可复用以感知「项目是什么技术栈」。
