Add Traffic Simulation Script and Monitoring Documentation

[Morfusee]

1. Traffic Simulation Script

• New Code:
  • Implemented a Node.js script (simulation/index.js) to simulate real user behavior across the API.
  • Covers core flows: user registration, login, chat creation, message interactions, and cleanup.
• Environment Config:
  • Added .env.template for required simulation environment variables.
• Dependencies:
  • Created simulation/package.json and pnpm-lock.yaml with dotenv for environment handling.
• Usage:
  • Provides a realistic load and interaction model to test performance and monitor metrics under simulated stress.
