Abstract driver trait for calculator interactions

This trait defines the interface that both TUI and WASM drivers implement, enabling unified test specifications that work on any platform.

§Example

// The abstract test specification
async fn verify_calculation<D: CalculatorDriver>(driver: &mut D) {
    driver.enter_expression("10 * (5 + 5)").await;
    assert_eq!(driver.get_result().await, "100");
}

// TUI test
#[test]
fn test_tui() {
    let mut driver = TuiDriver::new();
    block_on(verify_calculation(&mut driver));
}

// WASM test
#[wasm_bindgen_test]
async fn test_wasm() {
    let mut driver = WasmDriver::new().await;
    verify_calculation(&mut driver).await;
}
