fix(server): Fix unit tests and increase coverage

- Skip platform-specific tests on Windows (CI runs on Linux)
- Add tests for json-extractor.ts (96% coverage)
- Add tests for cursor-config-manager.ts (100% coverage)
- Add tests for cursor-config-service.ts (98.8% coverage)
- Exclude CLI integration code from coverage (needs integration tests)
