add: visual result card + HD screenshot script

- 成就卡片模板 (templates/result-card.html): SVG圆环进度、最大突破区、
  8维度色块网格、游戏化文案，身份感设计驱动分享
- 高清截图脚本 (scripts/screenshot.mjs): 2x deviceScaleFactor、
  精准截取 .card 元素、截完自动 open 打开
- 示例图放入 assets/ 供 README 引用
- SKILL.md 更新: 改名 darwin-skill、新增成果卡片生成流程章节

 区别：增加了人在回路（autoresearch是全自主的，skill优化需要人的判断力），以及双重评估机制（结构+效果），因为skill的「好坏」比loss数值更微妙。

+
+## 成果卡片生成（Result Card）
+
+每个skill优化完成后（或全量汇总后），自动生成视觉成果卡片，截图保存为PNG。
+
+### 卡片模板
+
+模板位置：`templates/result-card.html`
+
+3种风格，每次随机选择一种：
+
+| 风格 | CSS类 | URL hash | 视觉特点 |
+|------|--------|----------|---------|
+| Warm Swiss | `.theme-swiss` | `#swiss` | 暖白底+赤陶橙，Inter字体，干净网格 |
+| Dark Terminal | `.theme-terminal` | `#terminal` | 近黑底+荧光绿，等宽字体，扫描线 |
+| Newspaper | `.theme-newspaper` | `#newspaper` | 暖白纸+深红，衬线字体，双栏编辑风 |
+
+### 生成流程
+
+```
+1. 复制 templates/result-card.html 到临时工作文件
+2. 用 sed/编辑工具 替换占位数据：
+   - data-field="skill-name" → 实际skill名
+   - data-field="score-before/after/delta" → 实际分数
+   - 8个维度的 dim-bar-before/after width → 实际百分比
+   - data-field="improvement-1/2/3" → 实际改进摘要
+   - data-field="date" → 当前日期
+3. 随机选择风格：hash 设为 swiss/terminal/newspaper 之一
+4. 用 Playwright 截图：
+   npx playwright screenshot "file:///path/to/card.html#[theme]" \
+     output.png --viewport-size=960,1280 --wait-for-timeout=2000
+5. 提示用户查看成果卡片 PNG
+```
+
+### 何时生成
+
+- **单skill卡片**：每个skill优化完成后，展示该skill的分数变化
+- **总览卡片**：全部优化完成后（Phase 3），展示全局战绩
+
+### 品牌元素
+
+- 顶部：Darwin.skill 品牌标识 + 日期
+- 底部：「Train your Skills like you train your models」+ github.com/alchaincyf/darwin-skill
