25cb7164c7 Comprehensive legacy cleanup and architecture consolidation
Summary of Changes:

MOVED TO ARCHIVE:
- core/hakmem_tiny_legacy_slow_box.inc → archive/
  * Slow path legacy code preserved for reference
  * Superseded by Gatekeeper Box architecture

- core/superslab_allocate.c → archive/superslab_allocate_legacy.c
  * Legacy SuperSlab allocation implementation
  * Functionality integrated into new Box system

- core/superslab_head.c → archive/superslab_head_legacy.c
  * Legacy slab head management
  * Refactored through Box architecture

REMOVED DEAD CODE:
- Eliminated unused allocation policy variants from ss_allocation_box.c
  * Reduced from 127+ lines of conditional logic to focused implementation
  * Removed: old policy branches, unused allocation strategies
  * Kept: current Box-based allocation path

ADDED NEW INFRASTRUCTURE:
- core/superslab_head_stub.c (41 lines)
  * Minimal stub for backward compatibility
  * Delegates to new architecture

- Enhanced core/superslab_cache.c (75 lines added)
  * Added missing API functions for cache management
  * Proper interface for SuperSlab cache integration

REFACTORED CORE SYSTEMS:
- core/hakmem_super_registry.c
  * Moved registration logic from scattered locations
  * Centralized SuperSlab registry management

- core/hakmem_tiny.c
  * Removed 27 lines of redundant initialization
  * Simplified through Box architecture

- core/hakmem_tiny_alloc.inc
  * Streamlined allocation path to use Gatekeeper
  * Removed legacy decision logic

- core/box/ss_allocation_box.c/h
  * Dramatically simplified allocation policy
  * Removed conditional branches for unused strategies
  * Focused on current Box-based approach

BUILD SYSTEM:
- Updated Makefile for archive structure
- Removed obsolete object file references
- Maintained build compatibility

SAFETY & TESTING:
- All deletions verified: no broken references
- Build verification: RELEASE=0 and RELEASE=1 pass
- Smoke tests: 100% pass rate
- Functional verification: allocation/free intact

Architecture Consolidation:
Before: Multiple overlapping allocation paths with legacy code branches
After:  Single unified path through Gatekeeper Boxes with clear architecture

Benefits:
- Reduced code size and complexity
- Improved maintainability
- Single source of truth for allocation logic
- Better diagnostic/observability hooks
- Foundation for future optimizations

9b0d746407 Phase 3d-B: TLS Cache Merge - Unified g_tls_sll[] structure (+12-18% expected)
Merge separate g_tls_sll_head[] and g_tls_sll_count[] arrays into unified
TinyTLSSLL struct to improve L1D cache locality. Expected performance gain:
+12-18% from reducing cache line splits (2 loads → 1 load per operation).

Changes:
- core/hakmem_tiny.h: Add TinyTLSSLL type (16B aligned, head+count+pad)
- core/hakmem_tiny.c: Replace separate arrays with g_tls_sll[8]
- core/box/tls_sll_box.h: Update Box API (13 sites) for unified access
- Updated 32+ files: All g_tls_sll_head[i] → g_tls_sll[i].head
- Updated 32+ files: All g_tls_sll_count[i] → g_tls_sll[i].count
- core/hakmem_tiny_integrity.h: Unified canary guards
- core/box/integrity_box.c: Simplified canary validation
- Makefile: Added core/box/tiny_sizeclass_hist_box.o to link

Build:  PASS (10K ops sanity test)
Warnings: Only pre-existing LTO type mismatches (unrelated)
