feat(phase161): Add MirAnalyzerBox implementation (Phase 161-2 基本実装)
Task先生による Phase 161-2 実装成果: **tools/hako_shared/mir_analyzer.hako** (375行) - MirAnalyzerBox: MIR JSON v1 パーサー＆アナライザー - Core Methods: - birth(mirJsonText): JSON パース＆キャッシュ - validateSchema(): MIR v1 構造検証 - summarize_function(funcIndex): メタデータ抽出 - count_phis(funcIndex): PHI 命令検出 - count_loops(funcIndex): CFG backward edge によるループ検出 **テストインフラ** - test_mir_analyzer.hako: テストハーネスフレームワーク - test_rep1_inline.hako: インラインテスト (rep1_if_simple) - rep1_if_simple.mir.json: MIR JSON テストデータ (8.5KB) - rep2_loop_simple.mir.json: ループパターンテストデータ (9.6KB) **箱理論適用** - 箱化: MirAnalyzerBox = MIR 分析専任（単一責務） - 境界: JsonParserBox との完全分離 - Fail-Fast: 明示的エラー、フォールバック無し - 遅延SG: _functions キャッシュ、オンデマンド計算 **発見された課題** - JsonParserBox._parse_number() 無限ループ問題（次タスクで対処） - VM ステップ予算超過でフル MIR JSON テスト一時ブロック Status: Phase 161-2 80%完了（コア実装OK、テスト検証はJsonParser修正後） Next: _parse_number() 修正 → Phase 161-2 テスト完了 → Phase 161-3 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
