wandering1 a6cdebde62 文档体系重组与 D-7 一致性门禁落地,清理芯片手册孤儿图片
- D-6 目录规范化:docs 根目录散落文档归入 UI设计/子系统设计/架构设计/审查记录/
  环境与部署/网络 等子目录,去掉目录名空格,重命名 嵌入式C语言代码规范_V1.0.md
- D-7 三档一致性门禁:新增 scripts/check_doc_links.py(链接存在性)、
  scripts/gen_task_table.py(FreeRTOS 任务表数值)、scripts/check_mem_numbers.py
  (内存/Flash 体积),均支持 --check/--write/--diff,pre-commit 钩子同步注册
- D-5 文档索引:新建 docs/README.md,新建 docs/文档规范.md 约束目录命名与链接写法
- D-1 芯片手册瘦身:删除 1069 张无引用孤儿图片(77.06 MB),
  docs/芯片手册 120 MB → 41 MB,已引用图片零断链
- 同步 C 源码注释中的文档路径引用(D-6 重组后),构建 0 错误 0 警告

"""生成 docs/images/存储栈分层.svg —— GD5F2GQ5UE 存储软件栈分层图(纯标准库)。
由 gen_arch_svg.py 复制而来(build() 与数据解耦,通用):每层一个圆角框(标题 + 说明),
层间单向下箭头。本图各层均为"单层单职责",故 chips 留空(只渲染标题 + 说明行)。
用法(仓库根目录,任意 python3):
python tools/arch_diagram/gen_storage_stack_svg.py
输出:
docs/images/存储栈分层.svg
改分层时:编辑本文件顶部的 L_* / ROWS / TITLE / SUB / FOOT 数据后重跑。
