acc64f2438 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%** |

4c986fa9d1 Feat: Add experimental TLS Bind Box path in Unified Cache 
- Added experimental path in unified_cache_refill to test ss_tls_bind_one for C7 class.
- Guarded by HAKMEM_WARM_TLS_BIND_C7 env var and debug build.
- Updated Page Box comments to clarify future TLS Bind Box integration.

45b2ccbe45 Refactor: Extract TLS Bind Box for unified slab binding 
- Created core/box/ss_tls_bind_box.h containing ss_tls_bind_one().
- Refactored superslab_refill() to use the new box.
- Updated signatures to avoid circular dependencies (tiny_self_u32).
- Added future integration points for Warm Pool and Page Box.

093f362231 Add Page Box layer for C7 class optimization 
- Implement tiny_page_box.c/h: per-thread page cache between UC and Shared Pool
- Integrate Page Box into Unified Cache refill path
- Remove legacy SuperSlab implementation (merged into smallmid)
- Add HAKMEM_TINY_PAGE_BOX_CLASSES env var for selective class enabling
- Update bench_random_mixed.c with Page Box statistics

Current status: Implementation safe, no regressions.
Page Box ON/OFF shows minimal difference - pool strategy needs tuning.
