Feat: CI Workflow Enhancement & Deployment Integration with PM2

[Programmer-RD-AI]

Purpose

This PR introduces enhancements to the CI workflow by integrating PM2 for process management and deployment automation. It also refactors the workflow to improve maintainability and efficiency.

Goals

• Improve the CI/CD pipeline by introducing a structured build-and-deploy job.
• Automate database migrations and seeding within the CI process.
• Enable PM2 process management for seamless application deployment.

Approach

• Updated GitHub Actions CI workflow (.github/workflows/CI.yml) to:
  • Add PM2-based deployment and restart.
  • Introduce database migration steps before deployment.
  • Ensure ESLint checks run properly before building the project.
• Added ecosystem.config.js for PM2 configuration, enabling efficient process management and auto-restart.
• Updated package.json scripts to support PM2 commands for easy process handling (pm2:start, pm2:reload, pm2:stop).
• Included TODO placeholders for deployment configurations, allowing customization for different environments.

Checklist

• Ensured no sensitive credentials are committed.
• Verified CI/CD pipeline runs successfully.
• Implemented best practices for process management using PM2.
• Added database migration and seeding as part of the workflow.

Test Environment

• OS: Ubuntu Latest
• Node.js: v20
• Database: PostgreSQL

This update ensures a stable, automated deployment process, reducing downtime and improving overall efficiency. 🚀
