feat(theme-studio): add gnus as a view package

mu4e renders the open message with gnus, so the article-view headers, quote levels, signature, and inline emphasis are all gnus faces, not mu4e ones. gnus ships them as bright greens on a dark background, and the theme had no way to reach them. I added gnus as a bespoke view package: the article-view face set in face_data.py with palette seeds that mirror the mu4e header treatment, a realistic preview (header block, emphasized body, an 11-level quoted reply chain, signature), and a #gnustest gate that asserts every emitted face is a real gnus face. Theming and exporting gnus in the studio retires the green in the live view.
