Workflow
1. Ensure clean working directory
git status
If there are uncommitted changes, ask user how to handle them.
2. Find active release branch
git branch -a | grep 'release/'
If no release branch exists, create one from develop first (see /release-procedure).
3. Update release branch
git checkout release/vX.Y.Z
git pull origin release/vX.Y.Z
4. Create work branch from release
git checkout -b feat/issue-{NUMBER}-{DESCRIPTION}
5. Confirm creation
git branch --show-current
