    /// This function serves as a bridge between async and sync code, automatically adapting its behavior:
    /// - With `async` feature: Returns a boxed future for later await
    /// - Without `async` feature: Blocks immediately using the global runtime
    ///
    /// # Examples
    ///
    /// ## Async usage (with `async` feature)
    /// ```ignore
    /// use wmill::Windmill;
    /// # #[tokio::main]
    /// # async fn main() -> anyhow::Result<()>{
    /// let wm = Windmill::default()?;
    /// let user = wm.call_api(wmill::apis::admin_api::get_user(&wm.client_config, &wm.workspace, "Bob"))?;
    /// println!("User details: {:?}", user);
    /// # Ok(())
    /// # }
    /// ```

    /// ## Sync usage (without `async` feature)
    /// ```ignore
    /// use wmill::Windmill;
    /// let wm = Windmill::new(Some("<TOKEN>".into()), Some("admins".into()), Some("http://localhost:5000/api".into()))?;
