openai/gpt-chat-latest → A (3:1)

Side A adds a coherent, lasting feature: explicit user-triggered Reddit entity fetching, persists full imported API payloads via a new `EntityImported` event, replays them into state, stores raw payloads alongside derived views, and adds tests plus configurable API/dotenv support. Side B is a large architectural migration from many REST endpoints to a batch RPC API with room/thread refactoring, but much of the patch is mechanical endpoint replacement and file movement, making its lasting substance less concentrated than A's end-to-end persistence and import design.
