Moe Charm (CI) 6199e9ba01 Phase 15 Box Separation: Fix wrapper domain check to prevent BenchMeta→CoreAlloc violation
Fix free() wrapper unconditionally routing ALL pointers to hak_free_at(),
causing Box boundary violations (BenchMeta slots[] entering CoreAlloc).

Solution: Add domain check in wrapper using 1-byte header inspection:
  - Non-page-aligned: Check ptr-1 for HEADER_MAGIC (0xa0/0xb0)
    - Hakmem Tiny → route to hak_free_at()
    - External/BenchMeta → route to __libc_free()
  - Page-aligned: Full classification (cannot safely check header)

Results:
  - 99.29% BenchMeta properly freed via __libc_free() 
  - 0.71% page-aligned fallthrough → ExternalGuard leak (acceptable)
  - No crashes (100K/500K iterations stable)
  - Performance: 15.3M ops/s (maintained)

Changes:
  - core/box/hak_wrappers.inc.h: Domain check logic (lines 227-256)
  - core/box/external_guard_box.h: Conservative leak prevention
  - core/hakmem_super_registry.h: SUPER_MAX_PROBE 8→32
  - PHASE15_WRAPPER_DOMAIN_CHECK_FIX.md: Comprehensive analysis

Root cause identified by user: LD_PRELOAD intercepts __libc_free(),
wrapper needs defense-in-depth to maintain Box boundaries.
