- Add HandleDeploy with command routing: status, start, rollback, history
- Add showDeployHelp with command descriptions and usage examples
- Add showDeployStatus to display environment status with version and last deploy timestamp
- Add startDeployment to initiate deployment with build, test, package, and Kubernetes deployment steps
- Add rollbackDeployment to revert to previous version with validation and
