~x-ai/grok-latest → A (3:1)

A removes a conflicting 1400-line duplicate forum.rs and lands a real module layout (forum/mod.rs plus feed, views, paginator, thread_morph, etc.), fixing Rust module-root ambiguity and making the forum HTML surface maintainable. B only rewrites tests.edn to a single ^test\\..+ suite—useful auto-discovery hygiene, but a small config change with far less lasting structural impact than A’s module split.
