### 🔧 Rust側修正
- AST utilities拡張(src/ast/utils.rs)
- MIR lowerers新設(src/mir/lowerers/)
- Parser制御フロー改善(src/parser/statements/control_flow.rs)
- Tokenizer識別子処理改善(src/tokenizer/lex_ident.rs)

### 📁 主要変更
- tools/hako_check/cli.hako - CLI改善
- tools/hako_check/hako_source_checker.hako - Checker core更新
- tools/hako_check/tests/ - NEW (テストケース追加)
- tools/hako_check/run_tests.sh - NEW (テストランナー)
- src/mir/lowerers/ - NEW (MIR lowering utilities)
