feat(plugins): ArrayBox/MapBoxプラグイン実装とPhase 10.1計画
🎯 革命的発見: プラグインC ABI = JIT→EXE変換の統一基盤 ## 主な変更点 - ArrayBoxプラグイン: get/set/push/size/is_empty実装 - MapBoxプラグイン: size/get/has実装（ROメソッドのみ） - Phase 10.1ドキュメント: プラグインBox統一化計画 - デモファイル3種: プラグイン動作確認用 ## 技術的詳細 - BID-FFI (Box ID Foreign Function Interface) 活用 - 既存のプラグインシステムでJIT/AOT統一可能 - スタティックリンクでオーバーヘッド解消 - "Everything is Box → Everything is Plugin → Everything is Executable" ## テスト済み - array_plugin_demo.nyash: 基本動作確認 ✅ - array_plugin_set_demo.nyash: set操作確認 ✅ - map_plugin_ro_demo.nyash: RO操作確認 ✅ 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
