// Module: CLI - Command Line Interface for Configuration-Based Builds
//
// This module provides the cargo-first CLI interface that enables triggering
// builds directly with the Cargo utility instead of shell scripts.
//
// RESPONSIBILITIES:
// ================
//
// Primary:
// - Parse command-line arguments for profile-based builds
// - Load and validate configuration from land-config.json
// - Resolve environment variables from configuration
// - Execute builds with resolved configuration
//
// Secondary:
// - Provide utility commands (--list-profiles, --show-profile)
// - Support dry-run mode for configuration preview
// - Enable profile aliases for quick access
//
// USAGE:
// ======
//
// Basic usage:
// ```bash
// cargo run --bin Maintain -- --profile debug-mountain
// ```
//
// List profiles:
// ```bash
// cargo run --bin Maintain -- --list-profiles
// ```
//
// Dry run:
// ```bash
// cargo run --bin Maintain -- --profile debug --dry-run
// ```
//
