/**
 * Administrative Features Test Runner - Agent D
 * 
 * Executes comprehensive E2E tests for administrative and operational systems
 * with proper GNOME desktop integration and MCP Playwright support
 * 
 * Features:
 * - Automatic GNOME session detection and configuration
 * - MCP Playwright integration for enhanced browser automation
 * - WordPress error detection and handling
 * - Comprehensive evidence collection (screenshots, logs, reports)
 * - Parallel test execution with proper isolation
 * 
 * Usage:
 *   node tests/scripts/run-administrative-features-tests.js [options]
 *   
 * Options:
 *   --headless        Run in headless mode (default: false in GNOME)
 *   --slow-mo=N       Slow motion delay in ms (default: 500 for headed)
 *   --timeout=N       Test timeout in ms (default: 45000)
 *   --screenshot      Take screenshots on all steps (default: false)
 *   --mcp-only        Run only MCP-powered tests
 *   --standard-only   Run only standard Playwright tests
 *   --environment=ENV Test environment (default: staging)
