openai/gpt-chat-latest → A (5:2)

Side A adds substantial new functionality: explicit user-triggered Reddit entity fetching, persistent `EntityImported` events with replay support, storage of raw API payloads plus derived views, configurable API/OAuth endpoints, dotenv loading, and integration/UI tests. Side B primarily changes the DSL syntax from trailing to leading vote explanations, updating the parser, documentation, UI formatting, and a large number of fixtures/tests to match; while cohesive, it is largely a syntax migration rather than adding comparable long-term capability.
