Batch-update Nix packages under packages/ in this nix-aura repo to their latest upstream versions. Use this skill whenever the user wants to update, bump, or check for new versions of packages in packages/ (ruby-build, leaf, agent-browser, or any future GitHub-sourced package). Also use when the user says "check for package updates", "bump packages", "update packages", "any new versions?", or asks about a specific package like "update leaf" / "bump ruby-build". Covers both pure source-only packages (mkDerivation with sha256) and Rust packages (also have cargoHash).
