Every commit must now carry a Signed-off-by trailer matching its
author, certifying the right to submit the change under the project's
MIT license (DCO 1.1, the Linux kernel mechanism). Enforcement is
strict at three layers: a commit-msg hook rejects unsigned commits
locally (scripts/install-git-hooks.sh), and the new DCO workflow
rejects every push and pull request containing one. Merge commits and
bot authors are exempt, matching standard DCO checks.
