When is it safe to clone an `anyhow::Error`, and what considerations should be made?

Cloning an `anyhow::Error` is generally safe if the underlying error types and any associated data are cheap to clone and do not contain references to shared resources that could become invalidated. Consider the size and complexity of the error chain. If the error only contains simple data types (e.g., strings, integers), cloning is often acceptable. However, if the error wraps types that manage external resources, avoid cloning it if possible, or carefully manage the lifetime of the resource and the clones.
