Ce Clean Gone Branches

After a PR merges and the remote branch gets deleted, you're often left with stale local branches cluttering your repo. This skill automates the cleanup by running git fetch with prune, finding branches marked as gone, and deleting them after you confirm. It's smart enough to handle worktrees too, removing them before deleting the branch so you don't end up with orphaned working directories. The confirmation step shows you exactly which branches will go, so you're never caught off guard. It's one of those maintenance tasks you know you should do regularly but always put off until your branch list becomes unmanageable.
