pptx-rs2 0.5.0

//! 集成测试：文本格式化端到端流程（TODO-041）。
//!
//! 验证 TextFrame / ParagraphFormat / Font / ColorFormat 视图 API
//! 从设置到 round-trip 的完整流程，确保关键 OOXML 元素不丢失。
//!
//! # 覆盖场景
//!
//! - Run 字体大小 / 加粗 / 斜体 / 下划线 / 删除线
//! - Run 颜色（RGB / 主题色）
//! - 段落对齐 / 行距
//! - 文本框锚定 / 自适应 / 边距
//! - 多段落多 Run 混合
//! - 东亚字体设置
