chore: apply clippy lints to public API

By default, clippy doesn't suggest changes if it would break the public API. Whilst a sensible default, it makes us miss certain opportunities to follow conventions correctly. When a new lint is added, we can always temporarily allow it and make a change in the next breaking release but I think it is better to be aware of the lint than having it automatically silenced.
