/// Generates a new age X25519 keypair.
///
/// This function creates a random identity using `age::x25519::Identity::generate()`,
/// extracts the corresponding recipient (public key), and wraps them into a [`KeyPair`].
/// The public key is validated to start with "age1".
///
/// # Returns
/// Returns a [`Result`] containing a [`KeyPair`] on success, or an [`crate::Error`] if validation fails.
///
/// # Example
/// ```
/// # use age_setup::build_keypair;
/// let kp = build_keypair().unwrap();
/// assert!(kp.public.expose().starts_with("age1"));
/// ```
