新增: Rust 数据模型 + 颜色纯函数 + ts-rs 类型同步(B1)
- model.rs: 全部数据结构(Deck/Slide/Element/Style/Theme/AiCfg/LibItem/PageTemplate/ChatMessage/Op/RichSegment) 所有结构体 derive Serialize/Deserialize/TS,自动生成 TS 类型到 bindings/types.ts - color.rs: 颜色解析纯函数(resolve_color/resolve_bg/is_dark_bg/shade/hex_to_rgb) 对应 store.ts 的颜色逻辑,23 个单元测试全部通过 - lib.rs: 新增 app_info IPC 命令 - ts-rs 自动生成的 bindings/types.ts 与手写 types.ts 类型一致

* color.rs — 颜色/背景解析纯函数（对应 store.ts 的颜色函数）
|

*
|

* 这些函数供 Rust 端的渲染/序列化使用（B2 store 迁移时调用）。
|

* 当前阶段保持与 TS 版本完全一致的逻辑。
