Add assistent-personas support and enhance model merging functionality

- Introduced `assistent-personas.yaml` to the project and updated the `.gitignore` accordingly.
- Implemented functions to seed and merge assistent personas from local files to the VM.
- Enhanced the model capture process to include merging of wanted models from the VM into `models.yaml`.
- Updated documentation to reflect changes in the assistent personas and model management processes.
