~anthropic/claude-sonnet-latest → A (3:2)

Side A delivers a coherent, self-contained UX/code improvement (grouped CLI panel, single border, hover-to-copy) plus a genuine correctness fix (JS-safe-quote assertion preventing broken onclick handlers), all with a clean diff. Side B is a large mechanical refactor (splitting forum.rs into files) that mostly moves code verbatim, reintroduces some duplicated inline JSON templating instead of reusing helper functions (arguably a slight regression), and bundles an unrelated sampling script, making its net lasting value less clear-cut despite its size.
