test: add L1 data generation + L2 classifier validation (58 tests)

Phase C-D complete: - test_l1_data_generation.py — 8 tests verifying generate_data across all P0 groups - test_l2_classifier.py — 16 existing + 34 P0 classification verification tests - hina/pipeline/__init__.py — export classify_program for cleaner imports Key findings: - Classifier correctly detects: CALL→子程序调用, CICS→online, DB→DB操作, ORGANIZATION IS→文件编成, DIVIDE→DIVIDE_50.0, ASCII/EBCDIC→编码转换 (keyword match) - Rule engine provides baseline 項目チェック(重複含まず) for programs without L1 keyword matches - SD keyword (SORT/MERGE sort-file) breaks Lark parser (known limitation) - Full regression: 749 passed (0 new failures)
