fix(entropy): _iter_files에서 .git/node_modules 제외 — total_file_count 2298→1645

audit_repository_entropy_v1._iter_files가 .git(628개) 포함으로
total_file_count=2298 > budget=2200 → FAIL 발생.
.git, node_modules, __pycache__ 등 제외 → gate=PASS (1645/2200).

동시 fix: spec/39 YAML ScannerError — note 필드의 'status: DONE' 따옴표 처리.
