Bug fixes found through statement benchmark testing: 1. grammar.lark: Add ASCENDING/DESCENDING KEY IS + INDEXED BY to occurs_clause — fixes HINA024 (SEARCH ALL) parsing crash 2. grammar.lark: Add SD (Sort Description) entry type to file_section — fixes HINA034 (SORT), ST01, ST02 parsing crashes 3. read.py parse_file_section(): Handle SD blocks alongside FD blocks — enables SORT/MERGE file structure extraction 4 previously crashing files now parse successfully: - HINA024.cbl (SEARCH ALL): paras=3, files=0 - HINA034.cbl (SORT): paras=1, files=3 - ST01_SORT.cbl: paras=2, files=3 - ST02_MERGE.cbl: paras=1, files=4 Regression: 749 passed (unchanged — classify_program internally caught the crashes, so tests already 'passed'; real improvement is in data quality: structure extraction now works for these programs)
