feat: Implement plugin singleton pattern with shutdown support
- Add singleton support for plugin boxes (e.g., CounterBox) - Implement shutdown_plugins_v2() for controlled plugin lifecycle - Plugin instances now shared across multiple new() calls - Shutdown properly releases and allows re-initialization - All singleton E2E tests passing ✅ ChatGPT5による高度なプラグインライフサイクル管理実装 - シングルトンパターンでプラグインインスタンス共有 - 明示的なshutdownでリソース解放と再初期化対応 - Nyashの統一ライフサイクルポリシー維持 Note: ast.rs test failures are due to rapid development pace - tests need updating for new BoxDeclaration fields (private_fields, public_fields) 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
