//! Use-case wrapper for the `hook` subcommand — the per-keystroke
//! dispatch that decides "insert a literal space", "expand the token
//! to the left of the cursor", or "no-op".
//!
//! Phase D D4a routes `cmd::hook` through this module so the cmd
//! layer doesn't import `crate::domain::hook` directly. See
//! `app::expand` for the rationale.
//!
//! The `HookAction` enum and the rendering function are re-exported
//! at `pub(crate)` so cmd code constructs the InsertSpace short-
//! circuit (oversized line, paste-pending, etc.) using a stable
//! re-export rather than a deep `crate::domain::hook::HookAction`
//! path.
