クリーンアップ: プロジェクト整理とGitHub公開準備

## 🧹 ルートディレクトリ整理
- batファイル(21個) → tools/windows/llvm-build-attempts/へ移動
- ログファイル → logs/archive/へ移動
- LLVM実行ファイル(計104MB) → .gitignoreに追加して削除

## 📝 .gitignore更新
- app_*_llvm, app_link, string_len_app を除外
- 大容量バイナリファイルのアップロード防止

## 🔧 追加のリファクタリング
- src/jit/lower/builder/tls.rs: TLS関連を独立モジュール化

## 📊 整理結果
- ルートディレクトリ: 0個の一時ファイル（完全クリーン）
- リポジトリサイズ: 189MB（適切）
- 最大追跡ファイル: 5.2MB（許容範囲内）

GitHub公開準備完了！🚀
