Tests cover: - Successful IPNS name resolution - 404 handling (name not found) - Rate limiting with Retry-After header - HTTP error handling (400, 500) - Network error retries with exponential backoff - CIDv0 (Qm) and CIDv1 (bafy/bafk) parsing - Invalid record handling Also adds ipns.controller.ts coverage threshold since sync endpoint has lower coverage (tested via integration tests).
