feat: Add VM instruction statistics and fix plugin TLV debugging

Major changes:
- Add --vm-stats and --vm-stats-json CLI flags for VM instruction profiling
- Implement instruction counting by opcode type with JSON output support
- Add enhanced TLV debug logging with NYASH_DEBUG_PLUGIN=1 environment variable
- Fix missing fields in CliConfig and ASTNode::BoxDeclaration for test compatibility
- Improve plugin method call error messages with argument count/type details

This enables MIR→VM conversion health checks and supports the Phase 8.6 VM optimization goals.

# 🎯 CURRENT TASK - 2025年8月20日
# 🎯 CURRENT TASK - 2025年8月23日刷新
## 📊 現在の状況
## ✅ 直近の完了
1. ドキュメント再編成の完了(構造刷新)
2. プラグインBoxFileBox基本実装とインタープリター統合
3. VM命令カウンタ時間計測のCLI化`--vm-stats`, `--vm-stats-json`とJSON出力対応
### ✅ 完了したタスク
1. **ドキュメント再編成** - 完全完了!
- 283ファイル → 4大カテゴリに整理
- Phaseファイルも統合済み
- 説明書/予定フォルダ削除済み
## 🚧 次にやること(再開方針)
2. **プラグインBox基本実装** (Phase 9.78c)
- FileBoxプラグイン実装済み
- インタープリター経由の呼び出し成功
- 基本的な引数/戻り値サポート追加ChatGPT5による
1) MIR→VMの健全化短期・最優先
- 現行MIR→VMのマッピング表を作成欠落/冗長/重複を可視化)
- サンプル/テストをVMで実行し、差分ログ例外系・returns_resultを確認
- 成果物: `docs/reference/architecture/mir-to-vm-mapping.md`(暫定
### 🚧 現在の課題
1. **Bashコマンドエラー問題**
- docs整理で現在のディレクトリが削除された影響
- セッション再起動が必要かも
2) VM×プラグインシステムのE2E検証短期
- `tests/e2e_plugin_filebox.rs` をVMでも通す`--features plugins`
- ケース: `new/close`, `open/read/write`, `copyFrom(handle)`、デリゲーション from Parent
- 成果物: テストグリーン+既知の制約を `VM_README.md` に明記
2. **E2Eテスト状況**tests/e2e_plugin_filebox.rs
- インタープリターテスト: ✅ 成功FileBox.close()が"ok"を返す)
- デリゲーションテスト: ❓ 未実装の可能性
- VMテスト: ❌ 失敗VMはまだプラグインBox未対応
3) 命令セットのダイエット中期目標26命令
- 実行統計(`--vm-stats --vm-stats-json`)でホット命令を特定
- 統合方針(例: TypeCheck/Castの整理、Array/Ref周りの集約、ExternCall→BoxCall移行
- 段階移行(互換エイリアス→削除)と回帰テスト整備
- 成果物: 26命令案ドラフト移行計画
### 🎯 次のタスクMIR→VM チェック / 命令最適化)
## ▶ 実行コマンド例
1) MIR→VM 変換の健全性チェック(短期)
- 現行 MIR 命令 → VM 命令のマッピング表を作成
- E2E/サンプルを VM バックエンドで実行し、MIR→VM 変換ログを収集
- 例外系・Result正規化returns_resultの経路を VM で確認
計測実行:
```bash
nyash --backend vm --vm-stats --vm-stats-json local_tests/test_hello.nyash > vm_stats.json
```
2) 命令使用実績の計測(短期)
- 実際に使用されている VM 命令を計測(実行ログ/カウンタ)
- 現行宣言33命令 → 実使用コア命令の抽出
VM×プラグインE2E:
```bash
cargo test -q --features plugins e2e_interpreter_plugin_filebox_close_void
cargo test -q --features plugins e2e_vm_plugin_filebox_close_void
```
3) 命令セットのダイエット検討(中期)
- 目標: 26命令docsの合意値
- 代替可能/統合可能な命令の提案と互換性影響の洗い出し
- 実験フラグで26命令版のVMを試作段階移行
MIRダンプ/検証:
```bash
nyash --dump-mir --mir-verbose examples/plugin_box_sample.nyash
nyash --verify examples/plugin_box_sample.nyash
```
4) ドキュメント更新(短期
- 現状の命令一覧と目標26命令の整合reference/architecture/
- 計測結果(使用頻度)と統合方針を追記
## 🔭 26命令ターゲットドラフトの方向性
コア(候補): Const / Copy / Load / Store / BinOp / UnaryOp / Compare / Jump / Branch / Phi / Call / BoxCall / NewBox / ArrayGet / ArraySet / RefNew / RefGet / RefSet / WeakNew / WeakLoad / BarrierRead / BarrierWrite / Return / Print or ExternCall(→BoxCall集約) + 2枠例外/await系のどちらか
### 📝 メモ
- ChatGPT5がプラグインBoxメソッド呼び出しに引数/戻り値サポートを追加
- TLV (Type-Length-Value) エンコーディングで引数をプラグインに渡す実装
- Rustの借用チェッカーとの格闘の跡が見られる複数回の修正
### 🔧 推奨アクション
1. VMバックエンドでの実行ログ化命令発行ログ/カウンタ)
2. マッピング表作成MIR→VMと欠落/冗長命令の洗い出し
3. 26命令案のPoCブランチ作成→E2Eで回帰確認
4. docs更新命令一覧、設計意図、移行戦略
補助: Debug/Nop/Safepointはビルドモードで有効化命令としては非中核に降格

最終更新: 2025年8月22日 03:30MIRVM/命令最適化タスク追加
最終更新: 2025年8月23日MIR/VM再フォーカス、26命令ダイエットへ
