kasl-cli 0.9.0

//! Main entry point for the kasl application.
//!
//! Handles initialization of the tracing system, command-line argument parsing, daemon mode execution, and update notifications.
//!
//! ## Features
//!
//! - **Daemon Mode**: Background process spawning for activity monitoring
//! - **Debug Logging**: Configurable tracing system for development
//! - **Update Notifications**: Automatic checking for application updates
//! - **CLI Dispatching**: Routes commands to appropriate handlers

/// Sets up logging, checks for daemon mode, shows update notifications,
/// and delegates to CLI handler for command execution.
