claude-commit-msg: stop Claude Code writing a bad commit subject

A Claude Code PreToolUse hook that checks the commit subject before the git commit command runs, and denies the tool call if the subject is wrong. Claude then rewrites the subject and tries again, instead of running into a rejected commit and having to recover from it.

It holds no rules of its own. It finds the message in the command and hands it to your existing commit-msg git hook, so there is one source of truth for the convention.

commit-msg: a Conventional Commits hook for git

A single bash hook that rejects commit subjects which do not follow Conventional Commits. It checks two things:

1. The subject matches type(scope): lowercase description, with no trailing period.
2. The subject is 72 characters or fewer.

Merge, revert, fixup, squash, and reapply subjects that git generates itself are skipped, since they are not yours to reformat.
