chore: Phase 25.2関連ドキュメント更新&レガシーテストアーカイブ整理
## ドキュメント更新 - CURRENT_TASK.md: Phase 25.2完了記録 - phase-25.1b/e/q/25.2 README更新 - json_v0_bridge/README.md新規追加 ## テストファイル整理 - vtable_*テストをtests/archive/に移動(6ファイル) - json_program_loop.rsテスト追加 ## コード整理 - プラグイン(egui/python-compiler)微修正 - benchmarks.rs, instance_v2.rs更新 - MIR関連ファイル微調整 ## 全体成果 Phase 25.2完了により: - LoopSnapshotMergeBox統一管理実装 - ValueId(1283)バグ根本解決 - ~35行コード削減(目標210行の16%) - 11テスト全部PASS、3実行テストケースPASS
