~anthropic/claude-sonnet-latest → A (6:4)

A delivers a focused, working feature improvement (grouped CLI panel, hover-to-copy, JS-injection safety assert) with corresponding CSS updates in both themes, and is self-contained. B's dev-script improvement (cargo-watch, persistent fixture dir) has real value for local dev, but it bundles in an unrelated and unexplained removal of room header markup (title, room id, garden link) in forum.rs, which looks like an accidental regression riding along with an otherwise tooling-only commit.
