re0-release

1Ship a release of this repo in one deliberate command: check a pending change against the shipping and releasing checklist, commit it, then tag and publish once confirmed.

3## Goal
4 
5A release lands complete and trustworthy: every checklist item met, the version bumped by the kind of change, a commit message that hands off without the diff, release notes in house style carried as the signed tag's message, and a published artifact the release workflow produced on its own. `re0-release` walks a pending change down that path. It calls `sip` when installed, applies commit-economy directly, and never calls another user-invoked skill. Committing and publishing are confirmed separately: the commit stays local and reversible, while tagging and pushing go public.

7It is **user-invoked**: shipping is a deliberate human action, so only the human runs it, once they have decided to ship.

9## Workflow
10 
111. **Check the checklist.** Read the pending diff against every applicable item of the Shipping checklist in the repository root's `AGENTS.md` (its Shipping section) except the version bump and the `sip` run, which steps 2 and 3 own. That section is the authority. Report any gap to the human and stop rather than guessing past it.
