feat(Deployment): Integrate Ansible deployment via PHP deployment pipeline

- Create AnsibleDeployStage using framework's Process module for secure command execution
- Integrate AnsibleDeployStage into DeploymentPipelineCommands for production deployments
- Add force_deploy flag support in Ansible playbook to override stale locks
- Use PHP deployment module as orchestrator (php console.php deploy:production)
- Fix ErrorAggregationInitializer to use Environment class instead of $_ENV superglobal

Architecture:
- BuildStage → AnsibleDeployStage → HealthCheckStage for production
- Process module provides timeout, error handling, and output capture
- Ansible playbook supports rollback via rollback-git-based.yml
- Zero-downtime deployments with health checks
