~x-ai/grok-latest → A (2:1)

A removes an entire UI action (ExpandNewThreadForm), its handler, tests, and a redundant home toolbar in favor of SSR’ing #new-thread-ui-slot like room pages—real consistency and less surface area. B improves cli_panel (multi-command grouping, click-to-copy rows, JS safety asserts) but is peripheral UX polish rather than a lasting structural fix.
