Implement comprehensive CI/CD pipeline with automated quality checks and deployment workflows

[claytoncollie]

This PR aims to implement a comprehensive CI/CD pipeline that enforces coding standards (ESLint, Stylelint, PHPCS), runs static analysis (PHPStan), performs security scans (TruffleHog, virus scanning), executes unit tests (Jest), and automates deployments to multiple environments (develop, staging, production). This robust pipeline will significantly increase adoption in client projects by providing automated quality gates that catch issues early, ensure consistent code quality across teams, and reduce manual deployment errors through standardized build and deployment processes. The modular job structure makes it easy to reuse and customize for different client requirements while maintaining enterprise-level security and quality standards.

Closes #304
