/// The single source of truth for the Tauri command registration list.
///
/// Both the desktop entry point (`main.rs`) and the mobile entry point
/// (`build_mobile_app` below) expand this macro, so the desktop and mobile
/// handler lists cannot drift: adding a `#[tauri::command]` and forgetting to
/// register it here is a build error, and omitting a command from one platform
/// is impossible because there is only one list. Paths are written as
/// `$crate::commands::*` so the macro resolves correctly whether it is invoked
/// from inside this crate (mobile) or from the `goingson_desktop` consumer crate
/// (the desktop binary).
