Module cli 

CLI utilities for command-line applications.

This module provides common patterns for CLI applications including:

• Reading input from files, stdin, or command-line arguments
• Writing output to files or stdout
• Formatting and printing results with different output formats
• Error handling and exit codes

The [repl] sub-module provides a shared REPL scaffold and is enabled via the repl crate feature.
