Publisher v1 ships

Six new publication kinds land in this release: flyer, brief, resume, newsletter (you are reading one), field_guide, and pamphlet. Each is shaped by the same (stash → cook → publication) loop — different kinds slot items into different layouts.

The publisher primitive

(page_model × geometry × grid × resolver × report_md_slot) — five axes, one design space. Adding a kind is a small named PR.

The agent stops being a conversation and starts being a publisher.
