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

* Phase 1 defines minimal types only. The concrete logic remains in
* `mir::loop_builder` and will be delegated/moved here in later phases.
* - 25.1e / 25.1q / 25.2 で LoopForm v2 + LoopSnapshotMergeBox に切り替え済み。
* - 現在の Run 時間経路AST / JSON frontは `loopform_builder.rs` を SSOT としており、
* 本モジュールは互換レイヤ(歴史的な隊列や分析用)としてのみ残している。
* - Phase 31.x 以降で段階的に削除予定。新しい PHI 実装をここに追加してはいけない。
