// CC Sesija A §2.5 — A10 onboarding flag shape contract test.
//
// The onboarding Tauri commands (is_first_launch / mark_first_launch_complete /
// reset_first_launch) are pure Rust with their own cargo test (already passing
// 1/1). This test validates the JS-side binding shape so the React-side
// useOnboarding fast-path doesn't drift from the Rust-side return type.
//
// Cross-language contract: Tauri commands return Rust Result<T, String>:
//   is_first_launch     → Result<bool>    (JS: Promise<boolean>)
//   mark_first_launch_  → Result<()>      (JS: Promise<void>)
//   reset_first_launch  → Result<()>      (JS: Promise<void>)
