Clean up stale branches that have been merged or are no longer needed.

Steps

1. List local branches to delete (excluding main, dev, gh-pages):

git branch | grep -v -E '^\*|main$|dev$|gh-pages$'

Report what will be deleted. If no branches found, say "No local branches to clean" and skip to step 3.

2. Delete local branches that are fully merged:

git branch -d <branch-name>

If a branch is not fully merged, report it to the user and ask whether to force-delete. Do NOT force-delete without confirmation.

3. List remote branches to delete (excluding main, dev, gh-pages, HEAD):

git branch -r | grep -v -E 'origin/main$|origin/dev$|origin/gh-pages$|origin/HEAD'

Report what will be deleted. If no branches found, say "No remote branches to clean" and skip to step 5.

4. Confirm with the user before deleting remote branches. Show the full list and wait for approval. Then delete:

git push origin --delete <branch-names>

5. Prune stale remote refs:

git remote prune origin

6. Report final state:

git branch        # local
git branch -r     # remote
