/**
* MCP SearXNG Server - Enhanced Comprehensive Test Suite
*
* This test suite validates the core functionality of all modular components
* and ensures high code coverage for production quality assurance.
*
* Features:
* - Comprehensive testing of all 8 core modules
* - Error handling and edge case validation
* - Environment configuration testing
* - Type safety and schema validation
* - Proxy configuration scenarios
* - Enhanced coverage with integration tests
*
* Run with: npm test (basic) or npm run test:coverage (with coverage report)
