feat: 添加页面级 enabled 参数支持幻灯片启用/禁用控制

Browse Source 
添加页面级 enabled 布尔参数，用于临时禁用整个幻灯片，无需删除或注释 YAML 内容。
与元素级 visible 条件渲染独立工作，提供两层控制机制。

主要变更：
- 在 yaml2pptx.py 主循环中检查 enabled 参数，跳过禁用的幻灯片
- 实现独立的 slide_index 计数器，准确统计实际渲染的幻灯片数量
- 在 yaml_loader.py 中添加 enabled 字段验证，确保类型为布尔值
- 添加 11 个测试用例，覆盖各种使用场景
- 更新 README.md 和 README_DEV.md 文档，说明 enabled 和 visible 的区别
- 创建新的 slide-enabled-control capability 规范
- 更新 template-system 规范，添加 enabled 字段支持

使用示例：
  slides:
    - template: title-slide
      vars:
        title: "正常页面"
    - enabled: false
      template: work-in-progress
      vars:
        title: "临时禁用的页面"

测试：所有 282 个单元测试通过
