Review playbook

CommitMessageRewriter

Proposes the correct squash-merge commit message for a PR, derived from the diff, and updates the proposal on each push.

On pull request open and on every push, reads the full diff and proposes the squash-merge commit message the PR should carry: conventional-commit type and scope derived from what actually changed, a subject line describing the effect rather than the activity, a body explaining why, and the correct BREAKING CHANGE footer when the diff contains one.
