refactor: 重组项目目录结构
以讲义内容为骨架迁移到标准目录格式： - officefile/ 主内容（12章 + 附录 + CC4SI补充） - dofile/ 代码示例（11个Python脚本） - data/ 图片资源 - output/ 生成输出（忽略） - Archive/ 归档旧目录（忽略） - .claude/skills/ 保留markdown-to-docx工具链 - .pandoc/ 保留CSL和本地化配置 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

模块化系统示例 (Modular System Example)
|
||||
========================================
|
||||
|
||||
本示例展示了空间智能系统的模块化设计原则。
|
||||
模块化是构建可维护、可扩展系统的基础。
|
||||
|
||||
核心概念:
|
||||
1. 关注点分离 - 每个模块负责特定功能
|
||||
2. 接口设计 - 定义清晰的模块间通信协议
|
||||
3. 依赖注入 - 降低模块间耦合
|
||||
4. 插件架构 - 支持动态扩展功能
