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%** |

Refactor: Extract 5 Box modules from hakmem_tiny.c (-52% size reduction)

Split hakmem_tiny.c (2081 lines) into focused modules for better maintainability.

## Changes

**hakmem_tiny.c**: 2081 → 995 lines (-1086 lines, -52% reduction)

## Extracted Modules (5 boxes)

1. **config_box** (211 lines)
   - Size class tables, integrity counters
   - Debug flags, benchmark macros
   - HAK_RET_ALLOC/HAK_STAT_FREE instrumentation

2. **publish_box** (419 lines)
   - Publish/Adopt counters and statistics
   - Bench mailbox, partial ring
   - Live cap/Hot slot management
   - TLS helper functions (tiny_tls_default_*)

3. **globals_box** (256 lines)
   - Global variable declarations (~70 variables)
   - TinyPool instance and initialization flag
   - TLS variables (g_tls_lists, g_fast_head, g_fast_count)
   - SuperSlab configuration (partial ring, empty reserves)
   - Adopt gate functions

4. **phase6_wrappers_box** (122 lines)
   - Phase 6 Box Theory wrapper layer
   - hak_tiny_alloc_fast_wrapper()
   - hak_tiny_free_fast_wrapper()
   - Diagnostic instrumentation

5. **ace_guard_box** (100 lines)
   - ACE Learning Layer (hkm_ace_set_drain_threshold)
   - FastCache API (tiny_fc_room, tiny_fc_push_bulk)
   - Tiny Guard debugging system (5 functions)

## Benefits

- **Readability**: Giant 2k file → focused 1k core + 5 coherent modules
- **Maintainability**: Each box has clear responsibility and boundaries
- **Build**: All modules compile successfully ✅

## Technical Details

- Phase 1: ChatGPT extracted config_box + publish_box (-625 lines)
- Phase 2-4: Claude extracted globals_box + phase6_wrappers_box + ace_guard_box (-461 lines)
- All extractions use .inc files (same translation unit, preserves static/TLS linkage)
- Fixed Makefile: Added tiny_sizeclass_hist_box.o to OBJS_BASE and BENCH_HAKMEM_OBJS_BASE
