openai/gpt-chat-latest → B (4:1)

Side B adds substantial offline tooling improvements: it refactors log replay, makes `scan` a fast parse-only pass, surfaces detailed `parse_error` information, and introduces `compile --ingest` to replay prior state and compile a single event from a log, with corresponding CLI, API, and test updates. Side A mainly improves the HTML CLI panel UX by grouping commands, enabling click-to-copy, and adding assertions that command strings are safe for embedding in single-quoted JavaScript, which is useful but has a narrower, presentation-focused impact.
