//! Build a `TempProject` — a self-cleaning temporary directory pre-populated
//! with files — and emit a `Report` describing the lifecycle.
//!
//! ```text
//! cargo run --example temp_project
//! ```
//!
//! The temp directory is removed when `project` is dropped. The example
//! prints the staged paths, asserts they exist on disk, then drops the
//! handle and confirms the cleanup.
