par-term 0.30.0

//! Application module for par-term
//!
//! This module contains the main application logic, including:
//! - `App`: Entry point that initializes and runs the event loop
//! - `WindowManager`: Manages multiple windows and coordinates menu events
//! - `WindowState`: Per-window state including terminal, renderer, and UI
