/**
 * Jest Worker Thread for Parallel Test Execution
 *
 * This module implements a Node.js worker thread that runs Jest tests
 * in parallel for improved performance. Each worker receives a batch of
 * test files and executes them independently, reporting results back to
 * the main thread.
 *
 * Key features:
 * - Parallel test execution using worker threads
 * - Jest CLI integration with custom configuration
 * - Robust error handling and process management
 * - Detailed result reporting with timing information
 * - Working directory management for test isolation
 *
 * Worker responsibilities:
 * - Execute assigned test files using Jest CLI
 * - Collect test results and performance metrics
 * - Report results back to main thread via postMessage
 * - Handle errors gracefully with detailed reporting
 *
 * Performance considerations:
 * - Isolated working directory to prevent conflicts
 * - Sequential test execution within worker (runInBand)
 * - Minimal logging to reduce I/O overhead
 * - Efficient result aggregation and reporting
