feat: 实现字体主题系统和东亚字体支持

实现完整的字体主题系统，支持可复用字体配置、预设类别和扩展属性。
同时修复中文字体渲染问题，确保 Source Han Sans 等东亚字体正确显示。

核心功能：
- 字体主题配置：metadata.fonts 和 fonts_default
- 三种引用方式：整体引用、继承覆盖、独立定义
- 预设字体类别：sans、serif、mono、cjk-sans、cjk-serif
- 扩展字体属性：family、underline、strikethrough、line_spacing、
  space_before、space_after、baseline、caps
- 表格字体字段：font 和 header_font 替代旧的 style.font_size
- 引用循环检测和属性继承链
- 模板字体继承支持

东亚字体修复：
- 添加 _set_font_with_eastasian() 方法
- 同时设置拉丁字体、东亚字体和复杂脚本字体
- 修复中文字符使用默认字体的问题

测试：
- 58 个单元测试覆盖所有字体系统功能
- 3 个集成测试验证端到端场景
- 移除旧语法相关测试

文档：
- 更新 README.md 添加字体主题系统使用说明
- 更新 README_DEV.md 添加技术文档
- 创建 4 个示例 YAML 文件
- 同步 delta specs 到主 specs

归档：
- 归档 font-theme-system 变更到 openspec/changes/archive/

+字体系统集成测试
+
+本测试文件包含字体主题系统的集成测试，验证完整的工作流程：
+
+1. 多行文本扩展属性应用
+   - 验证扩展属性（line_spacing、space_before、space_after）应用到所有段落
+   - 测试从 YAML 加载到渲染的完整流程
+
+2. 模板字体继承
+   - 验证模板元素继承 fonts_default
+   - 测试内联模板的字体配置
+
+3. 引用循环错误
+   - 验证循环引用在渲染时被检测并抛出错误
+   - 测试错误信息的准确性
+
+测试策略：
+- 使用临时 YAML 文件模拟真实场景
+- 测试完整的加载 → 解析 → 渲染流程
+- 验证错误处理和边界情况
+
+注意：
+- 这些测试验证字体系统与其他模块的集成
+- 单元测试在 test_font_system.py 中
+- 渲染器测试在 test_pptx_renderer.py 中
