openai/gpt-chat-latest → A (3:2)

Side A delivers a substantial new pairwise voting workflow: it adds a dedicated `/vote` page, bridge-aware pair selection (`suggest_next_pair_in_pool`), in-place UI morphing after votes, ID normalization via `ItemId::from_storage`, and accompanying unit/integration tests. Side B introduces useful infrastructure for explicit Reddit fetching and persistent raw entity imports, but much of the patch is architectural refactoring around fetch/storage; A's changes more directly add enduring application behavior and fix identifier consistency across voting and imports.
