fix: HINA 全类型缺陷修复 — SORT/CSV/ALT 3 个真实缺陷

Browse Source 
对抗性全类型测试发现的缺陷和修复:

缺陷1: SORT/MERGE L1 关键词太严格（漏检）
  - 旧: 'SORT ON KEY' / 'MERGE ON KEY'（精确字符串）
  - COBOL 中的真实写法: SORT WORK-FILE ON ASCENDING KEY ...
  - 新: 正则 SORT(?:\s+\S+)?\s+ON\s+(?:ASCENDING|DESCENDING)?KEY

缺陷2: CSV 假阳性（STRING/INSPECT 非CSV也触发）
  - 旧: has_string=True -> CSV合并
  - 新: 要求 has_csv_merge（STRING+逗号分隔）
  - 单纯字符串拼接不再触发 CSV 分类

缺陷3: ALTERNATE RECORD KEY 被 ORGANIZATION IS 覆盖
  - 旧: 文件编成先于替代索引（同确信度先者胜）
  - 新: 替代索引放前面（更具体的分类优先）

回归: 767 passed（0 new failures）
