feat: 型安全性向上とモダンなJavaScript記法の採用
- TypeScriptの厳密な型定義を追加（anyをすべて削除） - String.prototype.matchAllとUnicodeフラグ(/u)を採用 - while文での代入式をfor...ofループに置き換え - 絵文字の正規表現でUnicodeフラグを使用してサロゲートペア対応 - 非null assertion演算子を安全なnullish coalescing演算子に変更 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
