fix: 高密度テスト52/52通過 + SPACES figurative constant FP fix
COBOL技術者による高密度テスト（52 tests）実装: 発見・修正されたバグ: 1. WS-KEY = SPACES の figurative constant 比較が FP 原因 - _matches_key_comparison に figurative constant除外を追加 - 構造検知の信号4でも SPACES/ZERO 等を除外 - structural_matching で単一ファイルプログラムを除外 2. simple_vs_two_stage が常に単純マッチングを返していた - 実証拠なしでも0.5で返す → 他の分類を汚染 - 修正: file_count>=2 + IF + 比較証拠がない場合は unknown 3. simple_vs_two_stageテストを現実に合わせて更新 回帰: 767 passed（0 new failures） 高密度テスト: 52/52 PASS
