Clean Gone Branches

Remove local git branches that have been deleted from the remote.

Process

1. Update remote references

   • Run git fetch --prune.

2. Inspect local state

   • Run git branch -vv to find branches marked as [gone].
   • Run git worktree list to see whether any of those branches still have worktrees.

3. Remove worktrees first

   • For each [gone] branch that still has a worktree, remove the worktree before deleting the branch.

4. Delete the gone branches

   • Delete each local branch marked as [gone].

5. Report the result

   • List removed worktrees and deleted branches.
   • If there are no [gone] branches, report that nothing needed cleanup.
