Release brief

Turn a window of shipped work into a brief for a non-technical stakeholder — verified against what actually reached production, grouped by consequence, referenced back to issue-tracker IDs and pull request numbers, and delivered as a themed Artifact page or Markdown. Load this only when the user explicitly asks for such a brief — "write a release brief", "board update", "brief the client on this sprint", "stakeholder summary of what we shipped". Do not load it to answer what changed recently, to generate a changelog or technical release notes, to summarise a single pull request, or to write a commit message; answer those directly instead.
