//! Project type detection and hint conversion helpers.
//!
//! Responsibilities:
//! - Map CLI hints to detected project types and back.
//! - Infer project type from repo-root file heuristics.
//! - Report whether interactive terminal features are available.
//!
//! Not handled here:
//! - AGENTS.md rendering or persistence.
