//! Advanced deployment command module
//!
//! This module provides an intelligent deployment system that automatically
//! detects project types and configures deployment strategies accordingly.

/// Execute advanced deployment with automatic project detection
///
/// # Arguments
///
/// * `app_name` - Optional application name (will be detected from project if not provided)
/// * `port` - Optional port number (will use default based on project type if not provided)
/// * `app_dir` - Optional application directory (defaults to current directory)
/// * `config_path` - Optional path to xbp.json configuration file
/// * `debug` - Whether to enable debug output
///
/// # Returns
///
/// * `Ok(())` if deployment was successful
/// * `Err(String)` if deployment failed
