TypeScript client for HANA Query API with full type safety and error handling

/**
 * Comprehensive API Endpoint Test Script with Type Validation
 * 
 * Tests all available endpoints of the HANA Query API using the TypeScript client.
 * Validates the new consistent { data, metadata } response format for all endpoints.
 * 
 * Features:
 * - **Complete Endpoint Coverage**: All 9 API endpoints tested
 * - **Consistent Format Validation**: Ensures all methods return { data, metadata }
 * - **Runtime Type Validation**: Validates responses against TypeScript interfaces
 * - **Performance Metrics**: Request timing and validation performance
 * - **Enhanced Metadata Validation**: Validates system info, API details, and counts
 * - **Plan Validation Testing**: Tests new plan existence behavior
 * - **Error Scenario Testing**: Tests 404 vs empty array responses
 * - **Header Validation**: Validates X-Response-Time and X-Authorization-Response
 * 
 * New Format Validation:
 * - Health endpoint now returns system metadata (Node version, platform, etc.)
 * - Docs endpoint now returns API metadata (endpoint count, generation time, etc.)
 * - All endpoints consistently return { success, data, metadata } structure
 * - Headers contain timing and authorization info (not in response body)
 * 
 * Usage: node --experimental-strip-types test-all-endpoints.ts
 * 
 * @requires Node.js 24+ with --experimental-strip-types flag
