Configure Code Climate Quality (now Qlty) for repository-wide quality gates - duplication, complexity, similar-code, exclude_patterns. Covers both legacy `.codeclimate.yml` (Code Climate Velocity / GitHub integration) and the new `.qlty/qlty.toml` per the Qlty platform migration. Use when a repo needs duplication and complexity thresholds enforced on PRs, or when an existing `.codeclimate.yml` must be migrated to Qlty without losing its plugin and exclude settings.
