Add k6 Performance Testing Workflow

Overview

This PR adds automated performance testing to the NodeBB project using k6 (Grafana's modern load testing tool). The workflow automatically runs performance tests after successful VM deployments to ensure consistent application performance.

Workflow Integration

The new k6 workflow is designed to run after the existing VM Deploy workflow completes successfully:

Files Added/Modified

New Files:

• .github/workflows/k6-performance.yml - GitHub Actions workflow for k6 tests
• my-test.js - k6 performance test script

Modified Files:

• package.json - Added k6 test script and ES6 module support

Features

Automated Performance Testing

• Trigger: Runs automatically after successful VM deployments
• Manual Trigger: Can be triggered manually via GitHub Actions UI
• Branch Targeting: Configured for main branch deployments

The k6 workflow:

• Triggers after successful VM Deploy workflow completion
• Tests NodeBB performance with 10 virtual users for 30 seconds
• Uploads results as workflow artifacts
• Can be manually triggered for testing

Key Features

• Non-blocking: Runs after deployment, doesn't prevent releases
• Automated: No manual intervention required
• Safe: Only runs on successful deployments
• Informative: Provides performance metrics and artifacts

Test Configuration

export const options = {
  vus: 10,          // 10 concurrent users
  duration: '30s',   // 30-second test
};
