/**
 * CLI command to open the MCP Hub Lite web user interface in the default system browser.
 *
 * This command provides a convenient way for users to access the web-based management
 * interface without manually typing the URL. It automatically constructs the URL using
 * the specified host and port options, then opens it in the user's default browser.
 *
 * The command is designed to work with both local development instances and production
 * deployments, allowing users to easily access the UI regardless of the server configuration.
 *
 * Priority order for host and port resolution:
 * 1. Command line options (--host, --port)
 * 2. Environment variables (HOST, PORT)
 * 3. Configuration file settings
 * 4. Default values (localhost:7788)
 *
 * @example
 * ```bash
 * # Open UI with configured settings from .mcp-hub.json
 * mcp-hub-lite ui
 *
 * # Open UI on a specific port
 * mcp-hub-lite ui --port 7788
 *
 * # Open UI on a specific host and port
 * mcp-hub-lite ui --host 192.168.1.100 --port 8080
 *
 * # Using short option flags
 * mcp-hub-lite ui -p 7788 -h my-server.local
 *
 * # Using environment variables
 * PORT=9999 mcp-hub-lite ui
 * ```
 *
 * @command ui
 * @description Opens the MCP Hub Lite web UI in the default system browser
 * @option {string} -p, --port <port> - Port where the MCP Hub Lite server is running
 * @option {string} -h, --host <host> - Host where the MCP Hub Lite server is running
 * @throws {Error} If the browser fails to open or the system encounters an error during execution
 * @returns {Promise<void>} Resolves when the browser has been successfully opened
