SahihIslam AI Backend - 10,000 Concurrent User Load & Stress Testing Suite
========================================================================
Simulates 10,000 distinct real-world users sending concurrent traffic
to test server stability, throughput, latency, rate-limiting, and memory usage.
Test Suites Included:
1. Raw Event Loop & Concurrency Test (10,000 unique users on /)
2. Database Read & In-Memory Cache Test (10,000 unique users on /api/hadith-of-the-day & /api/ayah-of-the-day)
3. Rate Limiter & DoS Protection Test (Verifies 429 Too Many Requests defense)
4. Mixed Real-World Traffic Simulation (10,000 users browsing Quran, Hadith, Editions, and Status)
