chore(release): bump version to 1.3.1-4 (Beta)

PR #422 合并后 bump。本版本相对 v1.3.1-3-beta 累积修复：
- Windows 默认字号 'large'（fontScale.ts UA 检测）
- Windows 原生标题栏底色刷成白色，与 sidebar 视觉统一（DWM CAPTION_COLOR）
- 全平台玻璃统一：WindowChrome 撤销 PR #419 留下的"Windows 100% opaque +
  无 backdropFilter"分支，两平台用同一半透明 background + blur saturate(190%)，
  alpha 0.92 → 0.78 让玻璃感更明显但不过透
- Vocab 词条大圈再次根治：global.css button reset 补加 outline:none /
  min-width:0 / min-height:0 / box-sizing:border-box
- polish ROLE_BLOCK 撤销 b2325a27 回滚，恢复 7e60bdb5 8-条规则状态
- polish ROLE_BLOCK 「意图难判」规则改为强制结构化（用户拍板的新版）
