//! Slash-command dispatch and local-recall handoff for `ChatWidget`.
//!
//! `ChatComposer` parses slash input and stages recognized command text for local
//! Up-arrow recall before returning an input result. This module owns the app-level
//! dispatch step and records the staged entry once the command has been handled, so
//! slash-command recall follows the same submitted-input rule as ordinary text.
