Subject: [PATCH] fix: branch detection now correctly filters HEAD and arrow
 entries

- grep -v '\->' removes the 'origin/HEAD -> origin/main' line
- grep -v '^HEAD$' removes stray HEAD entries
- sed trims whitespace and strips 'origin/' prefix
- sort -u deduplicates across repos
- Result: only clean branch names like 'main', 'dev', 'Dev'
