Add commit message validator using Ruby and Lefthook

Enforce consistent commit messages with a small Ruby script and Lefthook: a commit-msg hook that reads .git/COMMIT_EDITMSG, validates prefixes like feat, fix, or docs against a regex, and rejects bad messages before they land. Full script and Lefthook config included.
