Moe Charm (CI) 5582cbc22c Refactor: Unified allocation macros + header validation
1. Archive unused backend files (ss_legacy/unified_backend_box.c/h)
   - These files were not linked in the build
   - Moved to archive/ to reduce confusion

2. Created HAK_RET_ALLOC_BLOCK macro for SuperSlab allocations
   - Replaces superslab_return_block() function
   - Consistent with existing HAK_RET_ALLOC pattern
   - Single source of truth for header writing
   - Defined in hakmem_tiny_superslab_internal.h

3. Added header validation on TLS SLL push
   - Detects blocks pushed without proper header
   - Enabled via HAKMEM_TINY_SLL_VALIDATE_HDR=1 (release)
   - Always on in debug builds
   - Logs first 10 violations with backtraces

Benefits:
- Easier to track allocation paths
- Catches header bugs at push time
- More maintainable macro-based design

Note: Larson bug still reproduces - header corruption occurs
before push validation can catch it.

// Box: Unified Backend (Phase 12)
// Purpose: Unified entry point for SuperSlab allocation (shared pool + legacy fallback)
//
// Responsibilities:
// - Single front-door for tiny-side SuperSlab allocations
// - Shared pool backend integration
// - Optional legacy fallback for compatibility
// - ENV-based policy control (HAKMEM_TINY_SS_SHARED, etc.)
//
// Dependencies:
// - ss_legacy_backend_box (legacy backend)
// - hakmem_shared_pool (shared pool backend)
//
// API:
// - hak_tiny_alloc_superslab_box() - unified entry point
// - hak_tiny_alloc_superslab_backend_shared() - shared pool backend
