R2: 40/40 覆盖 parametrized/division + 全comparator + jcl/executor + agents + runners + report

覆盖完成:
- parametrized/division.py (7IF) — 全3种分割比例
- comparator/rounding_detect.py (4IF) — 截断/精确/置信度
- comparator/aligner.py (3IF) — 空/单侧/双侧匹配
- comparator/normalizer.py (5IF) — EBCDIC/COMP3/日付
- jcl/executor.py (12IF) — 条件判定/SORT/空ジョブ
- agents/llm.py (3IF) — 初期化/呼出異常系
- agents/agent2_data.py (1IF) — デザイン呼出
- runners/data_writer.py (4IF) — JSON/バイナリ書出
- report/generator.py (5IF) — HTML/機械JSON

全件: 31/31モジュールがテストで参照済
