Phase 10.7 - JIT統計とイベント機能の完成
主要な実装: - PHI(b1)統計追跡: phi_total_slots/phi_b1_slotsをJSON出力 - 関数単位統計API: JitStatsBox.perFunction()で詳細統計取得 - JITイベントシステム: compile/execute/fallback/trapをJSONL形式で記録 - Store/Load命令対応: ローカル変数を含む関数のJIT実行が可能に 新しいBox: - JitStatsBox: JIT統計の取得 - JitConfigBox: JIT設定の管理（将来用） - JitEventsBox: イベントのJSONL出力（将来用） - JitPolicyBox: 実行ポリシー管理（将来用） CLI拡張: - --jit-exec, --jit-stats, --jit-dump等のフラグ追加 - --jit-directモードでの独立JIT実行 - NYASH_JIT_*環境変数によるきめ細かい制御 ドキュメント: - Phase 10.7実装計画の詳細化 - Phase 10.9 (ビルトインBox JIT) の計画追加 - JIT統計JSONスキーマ v1の仕様化 ChatGPT5との共同開発により、JIT基盤が大幅に強化されました。 次はPhase 10.9でビルトインBoxのJIT対応を進め、 Python統合（Phase 10.1）への道を開きます。 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
