Leaf skill that orchestrates ONE gitflow release: creates a release branch from develop inside an isolated worktree, bumps version files under the confirmed semver bump, generates release notes via generate-release-notes, tags the release, and opens Change Proposals merging release into main and develop. Exposes a QA regression gate for the devops persona: approved → proceed; rejected → fixes route to develop and cherry-pick into release, gate re-run. Spawned by the devops persona with clean context (target version, develop reference, platform); also invocable directly.
