clean_gone

## Your Task

You need to execute the following bash commands to clean up stale local branches that have been deleted from the remote repository.

## Commands to Execute

1. **First, list branches to identify any with [gone] status**
   Execute this command:
   ```bash
   git branch -v
   ```
   
   Note: Branches with a '+' prefix have associated worktrees and must have their worktrees removed before deletion.

2. **Next, identify worktrees that need to be removed for [gone] branches**
   Execute this command:
   ```bash
   git worktree list
   ```

3. **Finally, remove worktrees and delete [gone] branches (handles both regular and worktree branches)**
   Execute this command:
   ```bash
   # Process all [gone] branches, removing '+' prefix if present
   git branch -v | grep '\[gone\]' | sed 's/^[+* ]//' | awk '{print $1}' | while read branch; do
     echo "Processing branch: $branch"
     # Find and remove worktree if it exists
     worktree=$(git worktree list | grep "\\[$branch\\]" | awk '{print $1}')
     if [ ! -z "$worktree" ] && [ "$worktree" != "$(git rev-parse --show-toplevel)" ]; then
       echo "  Removing worktree: $worktree"
