Clean Branches

Remove local branches that have been deleted on the remote (marked [gone]), including any associated git worktrees.

Steps

Fetch and prune remote refs:
```
git fetch --prune
```
List branches to identify [gone] status:
```
git branch -v
```
Branches with a + prefix have associated worktrees that must be removed before deletion.
List worktrees for reference:
```
git worktree list
```

Remove worktrees and delete [gone] branches:

git branch -v | grep '\[gone\]' | sed 's/^[+* ]//' | awk '{print $1}' | while read branch; do
  echo "Processing branch: $branch"
  worktree=$(git worktree list | grep "\\[$branch\\]" | awk '{print $1}')
  if [ ! -z "$worktree" ] && [ "$worktree" != "$(git rev-parse --show-toplevel)" ]; then
    echo "  Removing worktree: $worktree"
    git worktree remove --force "$worktree"
  fi
  echo "  Deleting branch: $branch"
  git branch -D "$branch"
done

Report which branches and worktrees were removed. If none were [gone], say no cleanup was needed.
