fix: v1.3.1-4 Windows 字号/顶栏色/玻璃 + Vocab 大圈 + polish 回滚

[appergb]

User description

v1.3.1-3 用户验证后 surface 5 件事，一次性收。合并后 bump 1.3.1-4 + 发新 Beta tag。

5 件事

1. Windows 默认字号放大

fontScale.ts 检测 navigator UA 含 Windows 时新装默认 'large' (1.1x zoom)。已存 localStorage 偏好的老用户不受影响。

2. Windows 顶栏白色，与 sidebar 统一

lib.rs 重新引入 apply_windows_caption_color，DWM DWMWA_CAPTION_COLOR=35 (Win11 22H2+) 把原生标题栏底色刷成 0x00FFFFFF。pre-22H2 Win 静默 warn 不阻塞。

3. 全平台玻璃统一 & 玻璃感更明显

关键发现：PR #419 留下了一个"Windows 100% opaque background + 去 backdropFilter"分支——这就是 Windows sidebar 完全无玻璃感的根因。WindowChrome.tsx 两平台改用同一份半透明 background（alpha 0.92 → 0.78 略浊但不过透）+ blur(var(--ol-glass-blur-strong)) saturate(190%)。Windows 配合 apply_mica 透 Mica。

4. Vocab 词条大圈再次尝试根治

PR #421 加的 appearance: none 不够。global.css button reset 补加 outline:none / min-width:0 / min-height:0 / box-sizing:border-box——Windows Chromium UA style 给 button 多种默认值叠加才造成大圈。键盘焦点走 .ol-focus-ring + :focus-visible box-shadow 不被 outline:0 影响。

5. polish ROLE_BLOCK 撤回 b2325a2 回滚

用户确认 13:08 之前最近的 polish.rs commit (20756f7，含 7e60bdb refine) 表现正常。b2325a27 把 ROLE_BLOCK 改回 v1.2.24-9-beta 状态反而离用户认可的版本更远。改回 7e60bdb 的 8-条 ROLE_BLOCK 状态。

Test plan

• Windows 全新安装：默认字号 large（明显比 macOS medium 大）；老安装升级保留之前偏好
• Windows: 原生标题栏底色白色，与 sidebar 颜色统一
• Windows: sidebar 能透出 Mica 磨砂玻璃感
• macOS: sidebar 玻璃感比 v1.3.1-3 略浊，对比 background 更明显
• Windows: Settings → 词汇表 词条无大灰圈
• macOS / Windows: "清晰结构"模式对结构化输入输出双层 list

⚡ Recommended focus areas for review Focus Loss Removing outline globally from every button means any button that does not also get the new custom focus styles will have no visible keyboard focus indicator. A missed trigger or future button added without .ol-focus-ring will become inaccessible to keyboard users. outline: none; min-width: 0; min-height: 0; box-sizing: border-box; Prompt Drift If ROLE_BLOCK is still shared by all polish modes, this new fallback can push ambiguous transcripts toward forced structural output instead of preserving the original sentence flow. That risks reintroducing the over-structuring regression this rollback is trying to avoid. - 当用户意图难以判断或无法确认时，\u{4E0D}要强行推断，改为只做结构和句子化的强制整理，直接整理成结构化输出，确保实际输出与用户想要的结构一致，并尽量贴近用户的原意。\n\ - \u{4E0D}引用任何会话历史、上一段语音、项目上下文、外部知识或模型记忆；每次请求都是独立任务。";
