AskaEth 65ca0ed29a feat(design): 加 unlucky-design 令牌 crate(M3 色彩/排版/形状/动效/图标)
D26 把视觉基线锁到 Material 3 Expressive,本 crate 是「UI 整体性」的地基:
令牌唯一真源,后续 iced 页面只消费不新增。零第三方依赖、零 UI 框架依赖
(cargo tree -p unlucky-design --edges normal 只有它自己一行)。

- 色彩:49 个 M3 语义角色 × light/dark,种子色派生 6 条 tone 调色板;
  tone 轴严格用 CIELAB L*(偏差 ≤1),色相/彩度用 OKLCh 近似 CAM16 并在
  模块文档里写明口径与已知偏差(不宣称是标准 HCT 动态取色)
- 对比度:26 组文字对 × 6 组种子 × 2 模式全部 ≥4.5:1;3 条例外显式登记
  (Outline 非文字 3:1、OutlineVariant 装饰、SurfaceVariant 是容器色)
- 排版:M3 type scale 15 档 + 三平台字体族回退栈(只写族名,不内嵌受限字体)
- 形状/高程/动效:Expressive 形状刻度 + shape morph 数据、elevation 级别与
  surface container 映射、时长/缓动/弹簧(纯函数可采样)
- 图标:24 个从 Slint 版迁移的 SVG path + 4 个新增,IconKind 冻结只可末尾追加;
  写明 Slint 的 stroke-width 是绝对像素、SVG 是 viewBox 用户单位的语义差异,
  换算封装成 Icon::stroke_width
- 组件档位表:20 个组件的形状/高程/字体/动效一次取全

TODO(M63):elevation shadow 的 blur/offset/alpha 与四组弹簧参数是占位值,
接口先定、数值待玻璃视觉规格表(tower 已通告边界)。
