kasl-cli 1.0.2

//! System autostart management command.
//!
//! Provides cross-platform functionality for managing whether kasl automatically starts monitoring when the system boots.
//!
//! ## Features
//!
//! - **Cross-Platform Support**: Windows Task Scheduler, Linux systemd, macOS Launch Agents
//! - **Enable/Disable Toggle**: Simple on/off control for autostart functionality
//! - **Status Checking**: Query current autostart configuration
//! - **Privilege Management**: Handles different privilege levels appropriately
//!
//! ## Usage
//!
//! ```bash
//! # Enable autostart on boot
//! kasl autostart enable
//!
//! # Disable autostart
//! kasl autostart disable
//!
//! # Check current status
//! kasl autostart status
//! ```
