Research direction
Investigate the current CLI implementation (likely in Java) to identify where output is rendered. Look at related issue #892 for context on the existing CLI features. Determine if there is an existing library for color output (e.g., JLine) and how to add colors to specific parts like prompt, command text, result stream, and errors.
