19/// ArcBiMutatingFunction - thread-safe bi-mutating-function wrapper
20///
21/// A thread-safe, clonable bi-mutating-function wrapper suitable for multi-threaded
22/// scenarios. Can be called multiple times and shared across threads.
23///
24/// # Features
25///
26/// - **Based on**: `Arc<dyn Fn(&mut T, &mut U) -> R + Send + Sync>`
27/// - **Ownership**: Shared ownership via reference counting
28/// - **Reusability**: Can be called multiple times (borrows inputs mutably each time)
29/// - **Thread Safety**: Thread-safe (`Send + Sync` required)
30/// - **Clonable**: Cheap cloning via `Arc::clone`
