//! Application-level events used to coordinate UI actions.
//!
//! `AppEvent` is the internal message bus between UI components and the top-level `App` loop.
//! Widgets emit events to request actions that must be handled at the app layer (like opening
//! pickers, persisting configuration, or shutting down the agent), without needing direct access to
//! `App` internals.
//!
//! Exit is modelled explicitly via `AppEvent::Exit(ExitMode)` so callers can request shutdown-first
//! quits without reaching into the app loop or coupling to shutdown/exit sequencing.
