feat: implement rollback command for deployments

- Added a new `rollback` command to roll back deployments to their previous release.
- Introduced `findRollbackCandidates` and `rollbackDeployment` functions to handle rollback logic.
- Updated CLI command definitions to include the new `rollback` command with an alias.
- Enhanced deployment conversion to use resolved images for buildable services.
- Introduced a new `graph` module to visualize Kubernetes resources and their relationships.
- Added tests for the new rollback functionality and graph rendering.
- Updated package version to 1.3.0.
