openai/gpt-chat-latest → B (3:2)

Side B fixes link generation to use `display_path()` instead of stored full URLs for `left`, `right`, and `pool` parameters, aligning vote URLs with the user-facing path format, and adds an end-to-end test that exercises all 45 pairwise votes and verifies the resulting ranking. Side A is a targeted correctness fix that skips `stickied`/`pinned` Reddit posts during import with a focused unit test, but its impact is narrower than the combination of user-visible URL correctness and substantially stronger integration coverage in Side B.
