Clean up git branches

Remove stale Git branches from local and remote repositories

Automated cleanup of merged and stale branches while preserving main, dev, and gh-pages.

• · Git repository with merged branches
• · Protect list: main, dev, gh-pages

• · Summary table with counts: local branches deleted, remote branches deleted
• · Final state: remaining local and remote branches
• · Pruned stale refs from origin

• · git branch (list/delete local)
• · git push origin --delete (remove remote)
• · git remote prune (clean refs)

• · User in Git repository root
• · Origin remote configured
• · Merged status determinable via git branch -d

• · Force-delete required if branch not fully merged (user confirmation needed)
• · Stale remote refs orphaned if git remote prune not run
• · Protected branches accidentally deleted if filter regex broken

• · Explicit list/confirm/delete three-step workflow
• · User confirmation required before remote deletions
• · Force-delete decision deferred to user, not automated
• · Prune step included to clean orphaned refs
• · Final state reporting for verification
