Subject: [PATCH] Explicitly enable the serde `derive` feature

The buildpack uses serde's derive macros but `Cargo.toml` didn't enable the
`derive` feature; compilation only worked because libcnb happens to enable it
transitively.

Making this change in part to stop Claude reporting it when code
reviewing the repo for bugs and other potential improvements.
