takt/src/__tests__/clone.test.ts
nrslib 47612d9dcc refactor: agent-usecases / schema-loader の移動と pieceExecution の責務分割
- agent-usecases.ts を core/piece/ → agents/ へ移動
- schema-loader.ts を core/piece/ → infra/resources/ へ移動
- interactive-summary-types.ts を分離、shared/types/ ディレクトリを追加
- pieceExecution.ts を abortHandler / analyticsEmitter / iterationLimitHandler / outputFns / runMeta / sessionLogger に分割
- buildMergeFn を async → sync に変更(custom merge の file 戦略を削除)
- cleanupOrphanedClone にパストラバーサル保護を追加
- review-fix / frontend-review-fix ピースの IT テストを追加
