larust-core 0.7.0

//! A real, standalone app binary used only by
//! `tests/dev_reload_auto_enable.rs` - deliberately does **not** call
//! `.with_graceful_shutdown(...)` at all, to prove `Application::serve()`
//! auto-enables graceful shutdown plus the restart admin channel purely
//! from `LARUST_DEV_RELOAD` being set, with zero app-level opt-in
//! required (exactly the behavior `xr dev`'s own rebuild-on-save loop
//! depends on).

/// No app-specific `config/app.rs` exists for this fixture (it lives

/// `config_env` helpers without a circular dependency) - reads `APP_PORT`/
/// `APP_NAME` directly, the two fields the test harness
/// (`tests/dev_reload_auto_enable.rs`) overrides per run: a reserved port
/// to avoid collisions, and a unique `app_name` so this process and the
/// test's own admin-channel client agree on the same channel address.
/// Everything else falls back to `Config`'s own defaults.
