- **Phase 3**: Integration tests and transaction mechanism (config snapshot + failure rollback)
- **Phase 4**: Extracted Service layer (`services/{provider,mcp,config,speedtest}.rs`)
- **Phase 5**: Concurrency optimization (`RwLock` instead of `Mutex`, scoped guard to avoid deadlock)

**Frontend Refactoring (React + TypeScript)** - Completed 4-stage refactoring:

- **Stage 1**: Test infrastructure (vitest + MSW + @testing-library/react)
- **Stage 2**: Extracted custom hooks (`useProviderActions`, `useMcpActions`, `useSettings`, `useImportExport`, etc.)
- **Stage 3**: Component splitting and business logic extraction
- **Stage 4**: Code cleanup and formatting unification

**Testing System**:

- Hooks unit tests 100% coverage
- Integration tests covering key processes (App, SettingsDialog, MCP Panel)
- MSW mocking backend API to ensure test independence

**Code Quality**:

- Unified parameter format: All Tauri commands migrated to camelCase (Tauri 2 specification)
- `AppType` renamed to `AppId`: Semantically clearer
- Unified parsing with `FromStr` trait: Centralized `app` parameter parsing
- Eliminate code duplication: DRY violations cleanup
- Remove unused code: `missing_param` helper function, deprecated `tauri-api.ts`, redundant `KimiModelSelector` component

**Internal Optimizations**:

- **Removed Legacy Migration Logic**: v3.6 removed v1 config auto-migration and copy file scanning logic
  - ✅ **Impact**: Improved startup performance, cleaner code
  - ✅ **Compatibility**: v2 format configs fully compatible, no action required
  - ⚠️ **Note**: Users upgrading from v3.1.0 or earlier should first upgrade to v3.2.x or v3.5.x for one-time migration, then upgrade to v3.6
- **Command Parameter Standardization**: Backend unified to use `app` parameter (values: `claude` or `codex`)
  - ✅ **Impact**: More standardized code, friendlier error prompts
  - ✅ **Compatibility**: Frontend fully adapted, users don't need to care about this change

  - **Native system integration** without Chromium overhead
  - **Enhanced security** with Rust backend

### ✨ New Features

### 📦 Dependencies

- **Tauri**: 2.8.2
- **React**: 18.2.0

### 🔄 Migration Notes

For users upgrading from v2.x (Electron version):

- Configuration files remain compatible - no action required
- The app will automatically migrate your existing provider configurations
- Window position and size preferences have been reset to defaults

#### Backup on v1→v2 Migration (cc-switch internal config)

- When the app detects an old v1 config structure at `~/.cc-switch/config.json`, it now creates a timestamped backup before writing the new v2 structure.
- Backup location: `~/.cc-switch/config.v1.backup.<timestamp>.json`
- This only concerns cc-switch's own metadata file; your actual provider files under `~/.claude/` and `~/.codex/` are untouched.

### 🛠️ Development

- Added `pnpm typecheck` command for TypeScript validation
- Added `pnpm format` and `pnpm format:check` for code formatting
- Rust code now uses cargo fmt for consistent formatting
