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
