Prepare for a breaking change in the Rust compiler.

The soundness fix in rust-lang/rust#115008 will cause axum-starter to break, even though it is not unsound. The missing bound is very hard to abuse, but still a soundness hole in our type system.

It will likely take 12 weeks before a stable compiler with the soundness fix is shipped.
