//! REPL command dispatch — parses slash commands and returns actions.
//!
//! This module is shared between the TUI and headless entry points.
//! It parses the command string and returns a [`ReplAction`] enum that
//! the caller translates into UI-specific behavior.
//!
//! See [`crate`] module docs for the full command table.
