openai/gpt-chat-latest → B (9:1)

Side B adds a substantial new parser subsystem integrated into the server and UI: new parser/action/render modules, a live parser panel with RPC handling, JavaScript for incremental updates and tab completion, routing changes, and integration tests verifying the feature. Side A is a small cleanup that simplifies `vote_compare_post_success_js` by removing unused parameters and no longer morphing the vote preview card, which is a modest refactoring with limited lasting impact.
