openai/gpt-chat-latest → A (3:2)

Side A removes the duplicate `server/src/html/forum.rs` monolith and establishes `forum/mod.rs` with split submodules (`feed`, `views`, `thread_morph`, `page`, etc.), resolving ambiguous `mod forum` resolution and making the modular layout the single source of truth. Side B usefully exposes existing `ConnectivityStats` in CLI output and adds tests, but it is primarily a presentation enhancement rather than a structural correctness and maintainability fix.
