refactor: MIR Builder Phase 1 - モジュール分割準備完了

【Phase 1完了内容】
- src/mir/builder/ ディレクトリ構造作成
- MirBuilder コア機能を core.rs に分離(8関数実装済み)
- 責務別モジュール準備(expressions/statements/control_flow/box_handlers)
- ビルド確認: 新構造でコンパイル正常完了

【技術詳細】
- MirBuilder本体 + emit_instruction/emit_type_check等コア機能
- プレースホルダー実装でビルド安全性確保
- CURRENT_TASK.md更新(Phase 1完了状況記録)
- 49関数/1547行の段階的分割準備

【次のPhase】
- Phase 2: 実際の関数移動(expressions.rs最優先)
- 慎重アプローチ: デッドコード削除は後回し
