Update CLI and ModelDialog to enhance functionality and user experience. Modify interrogation command in CLI for improved output generation, adjust model settings in ModelDialog for better reasoning effort, and introduce a new plugin structure in plan.md for LLM integration in Roundcube. Add spinner functionality in InkApp for loading states and improve error handling in read_file.js to ensure proper line breaks in file content output.
