Phase ML1: Pool v1 memset 89.73% overhead 軽量化 (+15.34% improvement)
## Summary
- ChatGPT により bench_profile.h の setenv segfault を修正（RTLD_NEXT 経由に切り替え）
- core/box/pool_zero_mode_box.h 新設：ENV キャッシュ経由で ZERO_MODE を統一管理
- core/hakmem_pool.c で zero mode に応じた memset 制御（FULL/header/off）
- A/B テスト結果：ZERO_MODE=header で +15.34% improvement（1M iterations, C6-heavy）
## Files Modified
- core/box/pool_api.inc.h: pool_zero_mode_box.h include
- core/bench_profile.h: glibc setenv → malloc+putenv（segfault 回避）
- core/hakmem_pool.c: zero mode 参照・制御ロジック
- core/box/pool_zero_mode_box.h (新設): enum/getter
- CURRENT_TASK.md: Phase ML1 結果記載
## Test Results
| Iterations | ZERO_MODE=full | ZERO_MODE=header | Improvement |
|-----------|----------------|-----------------|------------|
| 10K | 3.06 M ops/s | 3.17 M ops/s | +3.65% |
| 1M | 23.71 M ops/s | 27.34 M ops/s | **+15.34%** |
