create-release

Bump the Rust workspace version in root Cargo.toml, regenerate the lockfile, and open a draft PR on GitHub. Use this skill whenever the user says something like "create a release", "bump the version", "release vX.Y.Z", "prepare a release branch", or "bump workspace version". Trigger even if they just say "release X.Y.Z" or mention a semver version in a release context.
