Clean Branches

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

Steps

1. Fetch and prune remote refs:

   git fetch --prune
   

2. List branches to identify [gone] status:

   git branch -v
   

   Branches with a + prefix have associated worktrees that must be removed before deletion.

3. List worktrees for reference:

   git worktree list
   

4. 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
   

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