Build a Resilient Test Runner

## The Mission In this challenge, you are tasked with building a headless Test Runner engine. This engine will take a 'User Solution' (a function) and a 'Test Suite' (an array of test cases) and return a detailed execution report. ## Requirements 1. **Isolated Execution:** The engine must handle execution gracefully. 2. **Deep-Equality Assertions:** Support primitive types, nested objects, and arrays. 3. **Async Support:** Handle asynchronous solutions (Promises/Async-Await). 4. **Timeout Protection:** Implement a strict timeout of 1000ms per test case. 5. **Performance Metrics:** Track execution time for each individual test.
