"""
This module defines the command-line interface (CLI) for the CodeGraphContext application.
It uses the Typer library to create a user-friendly and well-documented CLI.
Commands:
- mcp setup: Runs an interactive wizard to configure the MCP client.
- mcp start: Launches the main MCP server.
- help: Displays help information.
- version: Show the installed version.
