Phase 122.5-126完了：ConsoleBox 品質改善・最適化・統合

Browse Source 
## 実装成果（Phase 122.5-126）

### Phase 122.5: nyash.toml method_id 修正
- println method_id を 2 → 1 に統一（log と同じ）
- TypeRegistry slot 400 との整合性確保

### Phase 123: ConsoleBox WASM/非WASM コード統一化
- マクロ define_console_impl! による重複排除
- 67行削減（27.3% 削減達成）
- ビルド成功・全テストパス

### Phase 124: VM Method Dispatch 統一化
- TypeRegistry ベースの統一ディスパッチ (dispatch_by_slot)
- String/Array/ConsoleBox を一元化
- 100行削減、メソッド解決の高速化

### Phase 125: 削除：deprecated builtin ConsoleBox
- src/box_factory/builtin_impls/console_box.rs 削除
- Plugin-only 移行で "Everything is Plugin" 実現
- 52行削減

### Phase 126: ドキュメント統合
- consolebox_complete_guide.md (27KB統合マスター)
- core_boxes_design/logging_policy/hako_logging_design 更新
- ~750行の navigation・cross-reference 改善

## 数値成果

- **総コード削減**: 219行
- **新規ドキュメント**: 1ファイル (+27KB)
- **更新ドキュメント**: 6ファイル (+~750行)
- **テスト**: Phase 120 representative tests ✅ PASS
- **ビルド**: Zero errors

## 設計原則の完全実現

✅ println/log エイリアス統一（Phase 122）
✅ WASM/非WASM 統一化（Phase 123）
✅ TypeRegistry 統合（Phase 124）
✅ Plugin-only 移行（Phase 125）
✅ ドキュメント統合（Phase 126）
