//! `dotzuki run` — boot a zero-Rust game project and play it.
//!
//! Window mode (default) opens a 320×240 (scaled) winit/pixels window via
//! `dotzuki_app`; `--headless` drives the game windowless for CI smoke tests,
//! optionally dumping the final frame to a PNG. `--watch` (windowed only)
//! hot-reloads scenes and the current map as files change on disk. A valid
//! save file (`<project>/.dotzuki-save.json`) resumes on boot — `--fresh`
//! ignores it, `--save-file` relocates it; windowed runs write saves at
//! stable points, headless runs only with `--save`.
