~x-ai/grok-latest → A (2:1)

A restores broken OAuth/Reddit HttpServer mocks with concrete correctness fixes (regex split on '=', getRequestBody, 302 content-length 0, nil-safe token/state, handler try/catch) plus auth E2E helper fixes so Playwright login works again—foundational test infrastructure. B is a solid, well-tested UX feature (CopyGardenRank + markdown formatting and UI wiring) but additive convenience rather than unblocking critical auth flows.
