agpm-cli 0.4.14

//! AGPM CLI entry point
//!
//! This is the main executable for the AGent Package Manager.
//! It handles command-line argument parsing, error display, and command execution.
//!
//! The CLI supports various commands for managing Claude Code resources:
//! - `init` - Initialize a new agpm.toml manifest
//! - `install` - Install dependencies from agpm.toml
//! - `update` - Update dependencies within version constraints
//! - `list` - List installed resources
//! - `validate` - Validate manifest and lockfile
//! - `cache` - Manage the global Git cache
//! - `config` - Manage global configuration
//! - `add` - Add sources or dependencies to manifest
//! - `remove` - Remove sources or dependencies from manifest
