feat: add COBOL statement benchmark plan and 34 P0 sample programs

- docs/cobol-statement-benchmark-plan.md — full coverage matrix and gap analysis - 34 P0 COBOL samples: arithmetic(9), move(5), file(6), control(6), inspect(3), search(2), perform(3) - test-data/validate_statements.py — automatic validation script - Validation: 34/34 samples pass preprocess + extract_structure
