feat: 快捷键录入交互重构 + ASR 模型体系升级（6 项按职责拆分）

[appergb]

User description

目标（一个 PR，六项按单一职责拆分）

1. feat(hotkey-recorder) — 快捷键录入交互重构：未展开主行只留键帽+箭头（录入入口统一在展开菜单），箭头恒靠最右，菜单动画改固定高度不再卡顿；ShortcutRecorder 支持 value=null 直接录入即启用
2. fix(update-button) — 检查更新按钮旋转方向（逆时针，与 ccw 图标一致）+ 按钮尺寸稳定（固定宽度居中、图标固定容器）
3. refactor(coding-agent) — Less Computer 后端/权限模式/模型选择改用官方 SelectLite（替代原生 select）
4. feat(asr-models) — 云端 ASR 模型预设下拉：加入千问 qwen3-asr-flash(-realtime/-filetrans)、fun-asr 新版本、paraformer；OpenAI 兼容厂商通用预设；与既有 unifiedBailian 机制融合
5. feat(local-asr) — 本地模型三板块重构（模型选择/下载与管理/其他）+ 下拉选择已下载模型 + 新增 Whisper Large V3 多语
6. chore(i18n) — 五语言新文案

兼容性影响

• 无破坏性变更；bailian 隐藏别名（bailian-qwen3-realtime / bailian-fun-asr-flash）逻辑保持
• CredentialField 新增可选 options prop，既有 provider/onValueChange 行为不变
• 新增模型为 Whisper 模式复用（Rust sherpa.rs 仅加条目），不影响现有模型

测试命令与结果

• npx tsc --noEmit ✅（beta 基线 + 本分支）
• npm run build（tsc + vite）✅
• cargo check --manifest-path src-tauri/Cargo.toml ✅（无新增 warning）
• npm run check:hotkey-side-modifiers ✅
• Tauri 打包（release dmg）✅ 已在本机安装验证（macOS aarch64）

证据

• macOS 手动验证：快捷键录入新交互（滑动动画/菜单）、检查更新按钮旋转方向、本地模型三板块布局
• 冲突解决说明：分支基于最新 origin/beta，ProvidersSection 与云端已有 unifiedBailian 机制融合（未覆盖云端改动）

链接

• 关联 AGENTS.md 提交规范；无 issue 编号（本轮为迭代反馈直接实现）

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review UI Regression The disable button in the expanded menu is now always rendered, even when no onDisable handler is provided. For the translation shortcut row in ShortcutsSection, for example, the menu shows a greyed-out "Disable" button with no tooltip (no disableHint is passed), which is confusing because the button is inert. Previously the button was hidden when onDisable was absent. Hide the button when onDisable is missing, or pass a hint explaining why it's disabled. <motion.button initial={{ y: 4, opacity: 0 }} animate={{ y: 0, opacity: 1 }} transition={{ duration: 0.16, ease: menuEase, delay: 0.06 }} whileHover={canDisable ? { y: -1 } : undefined} whileTap={canDisable ? { scale: 0.96 } : undefined} onClick={canDisable ? doDisable : undefined} title={canDisable ? undefined : disableHint} style={canDisable ? menuButtonStyle : disabledMenuButtonStyle} > {disableLabel ?? t('settings.shortcuts.disable', 'Disable')} </motion.button>
