Subject: [PATCH] =?UTF-8?q?fix(windows/theme):=20=E4=BF=AE=E5=A4=8DWindows?=
 =?UTF-8?q?=E6=B7=B1=E8=89=B2=E6=A8=A1=E5=BC=8F=E4=B8=8B=E6=96=87=E5=AD=97?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem:
Windows端深色模式部分文字回落黑色，背景与文字对比度不足无法阅读。

Changes:
1. index.html 增加 color‑scheme meta，适配WebView2原生控件
2. base.css 给 html/body/#root 增加 --foreground兜底颜色
3. 将深色选择器由 @media prefers-color-scheme / .dark 迁移至 [data‑theme‑type=dark]
4. theme.css 补齐缺失语义主题变量别名
5. chart.tsx 更新图表深色主题选择器

Validation:
bun run typecheck 通过
bun run lint：无新增错误，warning为存量mock文件未使用变量

Follow‑up:
1. Tailwind dark变体需要重定向到data‑theme‑type
2. radio‑group选中圆点视觉优化
3. code‑tokens还有部分硬编码浅色token待处理
