refactor: move drivers directory into mcontainer package

- Relocate goose driver to mcontainer/drivers/
- Update ConfigManager to dynamically scan for driver YAML files
- Add support for mc-driver.yaml instead of mai-driver.yaml
- Update Driver model to support init commands and other YAML fields
- Auto-discover drivers at runtime instead of hardcoding them
- Update documentation to reflect new directory structure
