fix: migrate deprecated code-supernova model ID to code-supernova-1-million

- Add model ID migration logic in RooHandler.getModel() to automatically convert the deprecated 'roo/code-supernova' model ID to 'roo/code-supernova-1-million'
- Add comprehensive test coverage for the migration logic
- Fixes #8880 where users get 404 errors when using the old model ID
