openai/gpt-chat-latest → A (4:1)

Side A makes the project's test configuration self-maintaining by replacing hand-enumerated test namespaces with a single auto-discovered `^test\..+` suite, ensuring new tests run automatically without updating `tests.edn` and reducing future maintenance. Side B adds a large new `reddit.rs` client and data model, but the patch only introduces a standalone file with no visible integration into the project, so its lasting project impact is less certain from the changes shown.
