feat(hako_check): Phase 153 - Dead code detection revival (JoinIR version)
Implement comprehensive dead code detection for hako_check with JoinIR
integration, following Phase 133/134/152 box-based modularity pattern.
## Key Achievements
1. **Comprehensive Inventory** (`phase153_hako_check_inventory.md`):
- Documented current hako_check architecture (872 lines)
- Analyzed existing HC011/HC012 rules
- Confirmed JoinIR-only pipeline (Phase 124)
- Identified Phase 153 opportunities
2. **DeadCodeAnalyzerBox** (`rule_dead_code.hako`):
- Unified HC019 rule (570+ lines)
- Method-level + box-level dead code detection
- DFS reachability from entrypoints
- Text-based analysis (no MIR JSON dependency for MVP)
- Heuristic-based false positive reduction
3. **CLI Integration** (`cli.hako`):
- Added `--dead-code` flag for comprehensive mode
- Added `--rules dead_code` for selective execution
- Compatible with --format (text/json-lsp/dot)
4. **Test Infrastructure**:
- HC019_dead_code test directory (ng/ok/expected.json)
- `hako_check_deadcode_smoke.sh` with 4 test cases
## Technical Details
- **Input**: Analysis IR (MapBox with methods/calls/boxes/entrypoints)
- **Output**: HC019 diagnostics
- **Algorithm**: Graph-based DFS reachability
- **Pattern**: Box-based modular architecture
- **No ENV vars**: CLI flags only
## Files Modified
- NEW: docs/development/current/main/phase153_hako_check_inventory.md
- NEW: tools/hako_check/rules/rule_dead_code.hako
- MOD: tools/hako_check/cli.hako
- NEW: tools/hako_check/tests/HC019_dead_code/
- NEW: tools/hako_check_deadcode_smoke.sh
- MOD: CURRENT_TASK.md
## Next Steps
- Phase 154+: MIR CFG integration for block-level detection
- Phase 160+: Integration with .hako JoinIR/MIR migration

Phase 10.7 - JIT統計とイベント機能の完成
主要な実装:
- PHI(b1)統計追跡: phi_total_slots/phi_b1_slotsをJSON出力
- 関数単位統計API: JitStatsBox.perFunction()で詳細統計取得
- JITイベントシステム: compile/execute/fallback/trapをJSONL形式で記録
- Store/Load命令対応: ローカル変数を含む関数のJIT実行が可能に
新しいBox:
- JitStatsBox: JIT統計の取得
- JitConfigBox: JIT設定の管理（将来用）
- JitEventsBox: イベントのJSONL出力（将来用）
- JitPolicyBox: 実行ポリシー管理（将来用）
CLI拡張:
- --jit-exec, --jit-stats, --jit-dump等のフラグ追加
- --jit-directモードでの独立JIT実行
- NYASH_JIT_*環境変数によるきめ細かい制御
ドキュメント:
- Phase 10.7実装計画の詳細化
- Phase 10.9 (ビルトインBox JIT) の計画追加
- JIT統計JSONスキーマ v1の仕様化
ChatGPT5との共同開発により、JIT基盤が大幅に強化されました。
次はPhase 10.9でビルトインBoxのJIT対応を進め、
Python統合（Phase 10.1）への道を開きます。
