- 支持四种图片适配模式：stretch、contain、cover、center - 支持背景色填充功能（contain 和 center 模式） - 支持文档级 DPI 配置（metadata.dpi） - PPTX 渲染器集成 Pillow 实现高质量图片处理 - HTML 渲染器使用 CSS object-fit 实现相同效果 - 添加完整的单元测试、集成测试和端到端测试 - 更新 README 文档和架构文档 - 模块化设计：utils/image_utils.py 图片处理工具模块 - 添加图片配置验证器：validators/image_config.py - 向后兼容：未指定 fit 时默认使用 stretch 模式
