fix(ui): add independent scroll containers to fix scroll wheel on Linux

Providers page was using DndContext which may interfere with scroll wheel
events on Linux/Ubuntu WebKitGTK. Added independent scroll containers
with `overflow-y-auto` to all main pages, matching the pattern already
used by the MCP panel which works correctly.

Changes:
- App.tsx: Wrap ProviderList in independent scroll container
- SkillsPage: Use consistent h-[calc(100vh-8rem)] layout
- SettingsPage: Add overflow-hidden and overflow-x-hidden for consistency

+## [3.8.0] - 2025-11-28
+
+### Major Updates
+
+- **Persistence architecture upgrade** - Moved from single JSON storage to SQLite + JSON dual-layer; added schema versioning, transactions, and SQL import/export; first launch auto-migrates `config.json` to SQLite while keeping originals safe.
+- **Brand new UI** - Full layout redesign, unified component/ConfirmDialog styles, smoother animations, overscroll disabled; Tailwind CSS downgraded to v3.4 for compatibility.
+- **Japanese language support** - UI now localized in Chinese/English/Japanese.
+
+### Added
+
+- **Skills recursive scanning** - Discovers nested `SKILL.md` files across multi-level directories; same-name skills allowed by full-path dedup.
+- **Provider icons** - Presets ship with default icons; custom icon colors; icons retained when duplicating providers.
+- **Auto launch on startup** - One-click enable/disable using Registry/LaunchAgent/XDG autostart.
+- **Provider preset** - Added MiniMax partner preset.
+- **Form validation** - Required fields get real-time validation and unified toast messaging.
+
+### Fixed
+
+- **Custom endpoints loss** - Switched provider updates to `UPDATE` to avoid cascade deletes from `INSERT OR REPLACE`.
+- **Gemini config writing** - Correctly writes custom env vars to `.env` and keeps auth configs isolated.
+- **Provider validation** - Handles missing current provider IDs and preserves icon fields on duplicate.
+- **Linux rendering** - Fixed WebKitGTK DMA-BUF rendering and preserved user `.desktop` customizations.
+- **Misc** - Removed redundant usage queries; corrected DMXAPI auth token field; restored missing deeplink translations; fixed usage script template init.
+
+### Technical
+
+- **Database modules** - Added `schema`, `backup`, `migration`, and DAO layers for providers/MCP/prompts/skills/settings.
+- **Service modularization** - Split provider service into live/auth/endpoints/usage modules; deeplink parsing/import logic modularized.
+- **Code cleanup** - Removed legacy JSON-era import/export, unused MCP types; unified error handling; tests migrated to SQLite backend and MSW handlers updated.
+
+### Migration Notes
+
+- First launch auto-migrates data from `config.json` to SQLite and device settings to `settings.json`; originals kept; error dialog on failure; dry-run supported.
+
+### Stats
+
+- 51 commits since v3.7.1; 207 files changed; +17,297 / -6,870 lines. See [release-note-v3.8.0](docs/release-note-v3.8.0-en.md) for details.

+
+**コア設計パターン**
+
+- **SSOT** (Single Source of Truth): すべてのデータを `~/.cc-switch/cc-switch.db`（SQLite）に集約
+- **二層ストレージ**: 同期データは SQLite、デバイスデータは JSON
+- **双方向同期**: 切り替え時はライブファイルへ書き込み、編集時はアクティブプロバイダから逆同期
+- **アトミック書き込み**: 一時ファイル + rename パターンで設定破損を防止
+- **並行安全**: Mutex で保護された DB 接続でレースを防ぐ
+- **レイヤードアーキテクチャ**: Commands → Services → DAO → Database を明確に分離
+
+**主要コンポーネント**
+
+- **ProviderService**: プロバイダの CRUD、切り替え、バックフィル、ソート
+- **McpService**: MCP サーバー管理、インポート/エクスポート、ライブファイル同期
+- **ConfigService**: 設定のインポート/エクスポート、バックアップローテーション
+- **SpeedtestService**: API エンドポイントの遅延計測
+
+**v3.6 リファクタリング**
+
+- バックエンド: エラーハンドリング → コマンド分割 → テスト → サービス層 → 並行性の 5 フェーズ
+- フロントエンド: テスト基盤 → hooks → コンポーネント → クリーンアップの 4 ステージ
+- テスト: hooks 100% カバレッジ + 統合テスト（vitest + MSW）

-# CC Switch 国际化功能说明
-
-## 已完成的工作
-
-1. **安装依赖**：添加了 `react-i18next` 和 `i18next` 包
-2. **配置国际化**：在 `src/i18n/` 目录下创建了配置文件
-3. **翻译文件**：创建了英文和中文翻译文件
-4. **组件更新**：替换了主要组件中的硬编码文案
-5. **语言切换器**：添加了语言切换按钮
-
-## 文件结构
-
-```
-src/
-├── i18n/
-│   ├── index.ts          # 国际化配置文件
-│   └── locales/
-│       ├── en.json       # 英文翻译
-│       └── zh.json       # 中文翻译
-├── components/
-│   └── LanguageSwitcher.tsx  # 语言切换组件
-└── main.tsx              # 导入国际化配置
-```
-
-## 默认语言设置
-
-- **默认语言**：英文 (en)
-- **回退语言**：英文 (en)
-
-## 使用方式
-
-1. 在组件中导入 `useTranslation`：
-   ```tsx
-   import { useTranslation } from 'react-i18next';
-
-   function MyComponent() {
-     const { t } = useTranslation();
-     return <div>{t('common.save')}</div>;
-   }
-   ```
-
-2. 切换语言：
-   ```tsx
-   const { i18n } = useTranslation();
-   i18n.changeLanguage('zh'); // 切换到中文
-   ```
-
-## 翻译键结构
-
-- `common.*` - 通用文案（保存、取消、设置等）
-- `header.*` - 头部相关文案
-- `provider.*` - 供应商相关文案
-- `notifications.*` - 通知消息
-- `settings.*` - 设置页面文案
-- `apps.*` - 应用名称
-- `console.*` - 控制台日志信息
-
-## 测试功能
-
-应用已添加了语言切换按钮（地球图标），点击可以在中英文之间切换，验证国际化功能是否正常工作。
-
-## 已更新的组件
-
-- ✅ App.tsx - 主应用组件
-- ✅ ConfirmDialog.tsx - 确认对话框
-- ✅ AddProviderModal.tsx - 添加供应商弹窗
-- ✅ EditProviderModal.tsx - 编辑供应商弹窗
-- ✅ ProviderList.tsx - 供应商列表
-- ✅ LanguageSwitcher.tsx - 语言切换器
-- ✅ settings/SettingsDialog.tsx - 设置对话框
-
-## 注意事项
-
-1. 所有新的文案都应该添加到翻译文件中，而不是硬编码
-2. 翻译键名应该有意义且结构化
-3. 可以通过修改 `src/i18n/index.ts` 中的 `lng` 配置来更改默认语言

+> Persistence Architecture Upgrade, Laying the Foundation for Cloud Sync
+
+**[中文版 →](release-note-v3.8.0-zh.md) | [日本語版 →](release-note-v3.8.0-ja.md)**
+
+---
+
+## Overview
+
+CC Switch v3.8.0 is a major architectural upgrade that restructures the data persistence layer and user interface, laying the foundation for future cloud sync and local proxy features.
+
+**Release Date**: 2025-11-28
+**Commits**: 51 commits since v3.7.1
+**Code Changes**: 207 files, +17,297 / -6,870 lines

+### Persistence Architecture Upgrade
+
+Migrated from single JSON file storage to SQLite + JSON dual-layer architecture for hierarchical data management.
+
+**Architecture Changes**:
+
+```

+                                 └─────────────────────────────────┘
+```
+
+**Dual-layer Structure Design**:
+
+| Layer      | Storage | Data Types                      | Sync Strategy   |
+| ---------- | ------- | ------------------------------- | --------------- |
+| Cloud Sync | SQLite  | Providers, MCP, Prompts, Skills | Future syncable |
+| Device     | JSON    | Window state, local paths       | Stays local     |
+
+**Technical Implementation**:
+
+- **Schema Version Management** - Supports database structure upgrade migrations
+- **SQL Import/Export** - `backup.rs` supports SQL dump for cloud storage
+- **Transaction Support** - SQLite native transactions ensure data consistency
+- **Auto Migration** - Automatically migrates from `config.json` on first launch
+
+**Modular Refactoring**:
+
+```
+database/
+├── mod.rs              Core Database struct and initialization
+├── schema.rs           Table definitions, schema version migrations
+├── backup.rs           SQL import/export, binary snapshot backup
+├── migration.rs        JSON → SQLite data migration engine

+    ├── skills.rs       Skills CRUD
+    └── settings.rs     Key-value settings storage
+```
+
+---
+

+
+**Supported Languages**:
+
+- Simplified Chinese
+- English
+- Japanese (New)
+
+---
+
+## New Features
+
+### Skills Recursive Scanning
+
+Skills management system now supports recursive scanning of repository directories, automatically discovering nested skill files.
+
+**Improvements**:
+
+- Support for multi-level directory structures
+- Automatic discovery of all `SKILL.md` files
+- Allow same-named skills from different repositories (using full path for deduplication)
+
+---
+
+### Provider Icon Configuration
+
+Provider presets now support custom icon configuration.
+
+**Features**:
+
+- Preset providers include default icons
+- Icon settings preserved when duplicating providers
+- Custom icon colors
+
+---
+
+### Enhanced Form Validation
+
+Provider forms now include required field validation with friendlier error messages.
+
+**Improvements**:
+
+- Real-time validation for required fields
+- Unified Toast notifications for validation errors
+- Clearer error messages
+
+---
+
+### Auto Launch on Startup
+
+Added auto-launch functionality supporting Windows, macOS, and Linux platforms.

+**Features**:
+
+- One-click enable/disable in settings
+- Implemented using platform-native APIs
+- Windows uses Registry, macOS uses LaunchAgent, Linux uses XDG autostart
+
+---
+
+### New Provider Presets
+
+- **MiniMax** - Official partner
+
+---
+
+## Bug Fixes
+
+### Critical Fixes
+
+**Custom Endpoints Lost Issue**
+
+Fixed an issue where custom request URLs were unexpectedly lost when updating providers.
+
+- Root Cause: `INSERT OR REPLACE` executes `DELETE + INSERT` under the hood in SQLite, triggering foreign key cascade deletion
+- Fix: Changed to use `UPDATE` statement for existing providers
+
+**Gemini Configuration Issues**
+
+- Fixed custom provider environment variables not correctly written to `.env` file
+- Fixed security auth config incorrectly written to other config files
+
+**Provider Validation Issues**
+
+- Fixed validation error when current provider ID doesn't exist
+- Fixed icon fields lost when duplicating providers
+
+### Platform Compatibility
+
+**Linux**
+
+- Resolved WebKitGTK DMA-BUF rendering issue
+- Preserve user `.desktop` file customizations
+
+### Other Fixes
+
+- Fixed redundant usage queries when switching apps
+- Fixed DMXAPI preset using wrong auth token field
+- Fixed missing translation keys in deeplink components
+- Fixed usage script template initialization logic
+
+---
+
+## Technical Improvements
+
+### Architecture Refactoring

+
+## Migration Guide
+
+### Upgrading from v3.7.x
+
+**Auto Migration** - Executes automatically on first launch:
+
+1. Detects if `config.json` exists
+2. Migrates all data to SQLite within a transaction
+3. Migrates device-level settings to `settings.json`
+4. Shows migration success notification
+
+**Data Safety**:
+
+- Original `config.json` file is preserved (not deleted)
+- Error dialog displayed on migration failure, `config.json` preserved
+- Supports Dry-run mode to verify migration logic
+
