chore: Add precommit hook to prevent committing to protected branches

[mattrunyon]

Figured since we have pre-commit hooks, we could add one to prevent accidentally committing to main and release branches.

I tested this w/ main and it doesn't let me commit without bypassing the hook. Doesn't prevent anything if you don't have the hooks obviously, but at least useful for those of us w/ admin so we don't accidentally do it.

I don't know how this would affect the release process. We might need to add SKIP=no-commit-to-branch to the release process if it's run locally w/ git that follows the pre-commit hooks

Looks good to me, but I'm not sure about the release part myself
