/**
 * SMI-632: BenchmarkRunner - Performance benchmark infrastructure
 * SMI-689: Enhanced with MemoryProfiler integration
 * SMI-1189: Refactored to use extracted modules

 * Features:
 * - Run benchmark suites
 * - Measure p50, p95, p99 latencies
 * - Memory usage tracking with MemoryProfiler
 * - Memory regression detection (fail if heap grows >10% vs baseline)
 * - Warm-up runs before measurement
 * - Statistical analysis (mean, stddev)
