🐛 fix(matrix-mana-bot): resolve QEMU emulation failure in CI

- Move pnpm overrides for cpu-features and ssh2 to root package.json
- These native deps cause illegal instruction errors under QEMU emulation

 ## Phase 3: Testing & Polish
 
 ### 3.1 E2E Tests für OAuth2/OIDC
-- **Status**: [ ] Offen
+- **Status**: [x] Erledigt (2026-02-01)
 - **Priorität**: 🟡 Mittel
 - **Problem**: ~35% Test Coverage, OIDC Flows nicht getestet
 - **Lösung**:
-  - E2E Tests mit Supertest
-  - OIDC Authorization Flow testen
-  - Token Refresh testen
+  - ✅ E2E Tests mit Supertest erstellt
+  - ✅ OIDC Authorization Flow Tests (Discovery, JWKS, Authorize, Token, UserInfo)
+  - ✅ Token Refresh Tests
+  - ✅ Auth Flow Tests (Registration, Login, Logout, Session, Validation)
+  - ✅ Rate Limiting Tests
+  - ✅ Security Tests (redirect_uri validation, token validation)
 - **Neue Dateien**:
-  - `test/e2e/oidc.e2e-spec.ts`
-  - `test/e2e/auth-flow.e2e-spec.ts`
+  - `test/e2e/oidc.e2e-spec.ts` - OIDC Provider Tests
+  - `test/e2e/auth-flow.e2e-spec.ts` - Authentication Flow Tests
+- **Hinweis**: Tests erfordern DATABASE_URL für Ausführung
 
 ### 3.2 OpenAPI/Swagger Dokumentation
-- **Status**: [ ] Offen
+- **Status**: [x] Erledigt (2026-02-01)
 - **Priorität**: 🟡 Mittel
 - **Problem**: Keine API-Dokumentation
 - **Lösung**:
-  - `@nestjs/swagger` integrieren
-  - DTOs mit Swagger Decorators
-  - `/api-docs` Endpoint
-- **Dateien**:
-  - `src/main.ts`
-  - Alle DTOs
+  - ✅ `@nestjs/swagger` zu dependencies hinzugefügt
+  - ✅ Swagger in main.ts konfiguriert
+  - ✅ `/api-docs` Endpoint unter http://localhost:3001/api-docs
+  - ✅ DTOs mit ApiProperty decorators (register, login)
+  - ✅ Controller mit ApiTags, ApiOperation, ApiResponse (auth, health)
+  - ✅ JWT Bearer Auth im Swagger UI konfiguriert
+- **Geänderte Dateien**:
+  - `package.json` - @nestjs/swagger hinzugefügt
+  - `src/main.ts` - Swagger Konfiguration
+  - `src/auth/auth.controller.ts` - API Decorators
