+//! Agent-profile use cases & reference catalogue (ARCHITECTURE §6, L5).
+//!
+//! This module owns the *profile* side of the AI runtime: detecting which CLIs
+//! are installed, persisting the chosen/edited/custom profiles, and exposing the
+//! pre-filled reference catalogue that seeds the first-run wizard. It talks only
+//! to the [`domain::ports::AgentRuntime`] and [`domain::ports::ProfileStore`]
+//! ports. Launching an agent (PTY + injection) is L6.
