Automates the full GitHub release workflow from analysis through changelog generation to PR creation, using only the gh CLI and git. It reads your commit history and code diffs, figures out whether you need a major, minor, or patch bump according to SemVer, formats a changelog in Keep a Changelog style, and opens a release PR. The first four steps are read-only reconnaissance so you can review the proposed version before anything gets written. Honestly most useful if you maintain libraries and are tired of manually comparing diffs to SemVer rules or formatting changelogs by hand. It leans heavily on code diff analysis over commit messages, which is the right call since commits lie but deleted functions don't.
