I would like to work on this issue because it ensures the crate is fully ready for publishing on crates.io, improving its usability and compliance. I have experience updating Cargo.toml metadata, verifying crate readiness with cargo publish --dry-run, and configuring CI workflows for releases. I can add all required fields, ensure the license and README are correct, and update the release workflow to include publishing.
