refactor: MIR instruction.rs 4-Phase大型リファクタリング完了（888→315行、64%削減）
Single Responsibility Principle適用による完全分離: - Phase 1: テスト分離 → instruction/tests.rs (196行) - Phase 2: Display実装分離 → instruction/display.rs (130行) - Phase 3: メソッド実装分離 → instruction/methods.rs (247行) - Phase 4: 統合テスト成功（全コンパイルエラー解決） 技術的成果: - MirInstruction enumを単一責任に集中 - 各実装が独立して保守可能な構造 - EffectMask::read→READ修正も完了 - ビルド成功確認済み（警告のみ） 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
