Release workflow for the Stave repository that confirms whether the next release is patch or minor before bumping the version, reviews the actual PR changes and PR description `Changes` sections in the release scope instead of relying on commit titles alone, generates release notes with `conventional-changelog`, and opens a pull request against `main` from a dedicated temporary release worktree so the user's original checkout stays on its original branch.
